N., first honey calm down. I'm going to go through your post point by point. Maybe because my parents were school teachers I did not have the kind of anxiety that you do but I do remember how hard it was to leave my daughter the second day of kindergarten, it seemed like such a long walk from the curb to the school door by the end of the week I no longer felt the need to chase after her.
Your post was long so mine will be too and also let me offer my ear if you want to run anything by me privately, please send me a note. My mother taught kindergarten for 30 years, my father middle school English. My first thing to share is that I thought my mother was mean when I was probably around middle school because she was strict with the students but you know what? They absolutely adored her, and when her children started having children, they requested that their kids have her for kindergarten. She has many families that still, more than 20 years after she retired keep in touch with her because they knew that she cared. Kids need limits and they also need to stretch their wings.
The vast majority of teachers are there because they honestly love kids and with three children who are now 9, 13 and 16, I have really not encountered a single teacher that was mean. A couple I would rather have done without, because they weren't the best teachers on the planet, but not one that was out right mean. Now, if your daughter should come home and tell you the teacher is mean, you need to remember that kids will say this when they don't like what is going on and you need to figure out if your daughter is trying to avoid dealing with a situation or has a real problem.
Schools will let you visit the classroom. Now, I do not recommend this the first week of school, the best thing you can do for your daughter is give her a hug and get out of the classroom as quickly as possible. Here's why. My daughter, after having been in a regular daycare from one year until she was 3 and at a pre-school after that actually cried the first day of kindergarten. At which time my mother (who flew down from Chicago for the event) immediately left the room and the building. She was fine minutes after we left and the problems my mother always had were with the parents that kept coming every day and making a big production about leaving. It will feel mean to you but you have to do it for them. The teacher will get them interested in something in the room and before you know it, the water works are gone and by the end of the first week they usually love school.
Parenting is not for the feignt-hearted, it takes a lot of courage and often doing things that seems more like sticking a knife into your heart than anything else but you need to do what you need to for your daughter not you. Now, say three weeks down the road your daughter tells you the teacher is mean. You ask why, if she seems to have valid concerns you ask to visit the classroom but you prepare your daughter before hand and tell her that you want to go watch her class but she has to pretend you are not there, that you cannot be a distraction to the students learning. So you see for yourself what is going on.
My kids know two things about me with school. They had better be telling the truth if something is going on and if there is a problem they get my full backing. Kids do need to know this but they also have to learn to solve their own problems, it is a fine line from sticking up on their behalf to teaching them you are always going to bail them out of things. Remember, be respectful in your dealings and be sure of what you are saying, they want to work with you to educate your child, and they do really care so don't be scared of them. They are just people, in my world growing up, they were the folks my parents played bridge with so good or bad, schools and teachers have never intimidated me.
Something positive you can also do is let the teacher know that you are available for any help you can give. I see from your profile that you are a SAHM, that is perfect, let her know you are available if she needs help in the classroom, needs papers run off, needs chaperones for field trips. And outside that, get involved with the PTA. One of my little secrets, both of my sons were in school with me in the strollers so by the time they hit school, not only did every single teacher in that building know me and my daughter, they knew my sons, including the security guard and those folks look out for your kids. Give them a word if they are going to get into trouble and just in general they just notice more if your kid is having a problem or something.
Also too, I saw a comment about getting to know the other parents. That is a godsend as well because if yours is having a problem, you call Sue and ask what is going on with Billy, gives you a better idea of whether the problem is real or just something your little one is having a hard time dealing with.
Now the shy thing. That one you just have to suck up. If she doesn't seem to be making friends, you encourage her to play with the other children, make a play date with one of her classmates so they can get to know each other outside of school. If you home school her, how is she ever going to make friends or get over the shyness?
Same things go with getting picked on. That is going to happen period but you can tell her that not all people are nice. With my daughter she had a couple of problems when she was around that age. I was honest with her and told her to avoid the particular girl and when she had to be in contact with her to be nice even if the girl was mean. I told her that sometimes there are things going on at home and then the kid takes it out on others. In one of these instances we later found out that the child was totally miserable with her home situation and a few years later she was one of my daughter's best friends. I just mentioned this thread to my daughter and she said that children need to develop a thick skin but keep a soft heart and they are better off learning this early.
She was also made fun of because she is half Hispanic and doesn't look it, so some of those problems were about that and she survived it and I think is more compassionate to other people for having gone through it, so even though it hurts to see your kids in pain, they grow from it and become better people if you give them the proper guidance. Now if your daughter is actually being bullied or a kid just won't stop with the picking, you talk to the teacher. If the teacher does not seem to be listening to your concerns you talk to the principal. If the principal is not listening you keep going up until you get the superintendent involved, period. Schools are legally obligated to take bullying seriously but you also need to make sure that they are.
On the hating school, your daughter has to sense your anxiety over this and if you don't start seeing it as a positive wonderful thing, she won't. So you need to be cheery and talk about how cool school is going to be, etc. so that she is in the right frame of mind when she gets there. Your daughter is going to see through it if you don't believe it, children are smart so one of the first things you do is realize that it IS a good thing and go from there. You know that you can always pull her out of school but if it is for this type of reason, it is a poor choice. And my daughter's additional contribution is that private school kids are as mean or meaner, so you are not sending her off to the wolves.
The bottom line, everything IS going to be okay. Children are resilient. You have given her a wonderful foundation and she will take that with her everywhere she goes. Most parents worry about their teenagers, I don't because even when they act like they are not listening they are, and while they have made a couple of bonehead choices, they have not been big ones, I think they are just too smart to make bad decisions that could really, really affect them badly.
And to me, this is perhaps the most important thing I have to say. I have always taught my kids that if they look at a situation, like going to a special class where they know no one, or camp or something, and they are scared because they don't want to look foolish or something, they can allow that fear to guide them and not do things, but they will miss out on a lot of things in their lives. So, you should suck it up, close your eyes and jump. Now, I wouldn't be much of a parent if I didn't practice what I preached. If you try to shelter your daughter from all pain in life, how will she ever grow up to live in a world where there is pain? What you are doing now is starting to give her the skills to deal with adversity that she will surely face in a safe and happy environment where she knows you are still there for her. As they get older, you do the same thing just let them take a little more on as they continue to mature and soon they will only turn to you when they really need you. And believe me, there are days when I wish my counseling office was closed, lol. You are a resource for your child, you cannot and should not live her life for her.
