Hi,
Believe me, you are not alone. I was talking with a friend who had read "1-2-3 Magic" by Thomas W. Phelan, Ph.D. because her son was (according to her) off the wall and did not listen or share. After hearing her thoughts on the method, I figured it wouldn't hurt to read the book myself.
I have been transitioning myself into using his method more and more and it really seems to be working. My daughter is almost 3. Personally, I feel a lot less stressed because the method is very calming since you are not having to yell. I can see that my daughter listens and I usually don't get past "2". Often times, all I have to say is "1" and her behavior then turns positive again.
But, just bear in mind that children imitate what they see. If there are a lot of hugs and kisses, they will often want to give the same. If there is a lot of yelling, they will communicate the same way.
Also, children are not born "sharers". They need to be taught how to share. As frustrating as it is watching your child hail claim to everything in sight and not be willing to share, it is normal.
As far as temper tantrums go, if you don't acknowledge them, they go away. Of course, you will want to be sure this tactic is done at home first. If you are out at the mall and a temper tantrum starts, you need to be willing to drop everything and just go (without yelling or saying a word). Once the child sees that temper tantrums get him/her what he/she wants, you will see more of them in the future.
The book is pretty amazing and goes into all sorts of scenarios. Check it out - I checked it out from our local library. I think you will find it helpful. But keep in mind, we all have our days and even 2-year olds can have a bad day and need to vent. After all, that is the age where they are between being a baby and a toddler. They want more independence, but also need guidence and limits, which 2-year olds find bothersome at times.
Finally, be sure that you have time AWAY from your child(ren). Even if it is just a bubble bath. It helps to be able to have adult interaction too, so be sure you have that as well - with your husband as well as friends.
Best of luck.
