I puked every day, at least 3 times, for 8 1/2 months. I worked in child care and could barely function. It was bad for me and I can only imagine how hard this was for you since it was obviously much, much worse.
I worked in the field of Developmental Disabilities for many years and was attacked by consumers on lots of occasions. When a person is institutionalized they become less of a person and tend to react badly when they are under stress. I don't blame these people for their actions. I ended up in the hospital ER once and the next day I totally broke down in class at college. I called my friend and met her at the Library and I couldn't go in the door. I'd be trapped and couldn't get out...I went in the hospital that day and got out a day later with meds to help with the anxiety and it took several years but I eventually just got over it. I have had no regular meds in years and, even though I still do some of my avoidance behaviors, I can usually function well in most situations.
I hate being trapped at signal lights unless I am in front on the right side so I can turn right after stop if I want to get out of traffic...I sit by the door in all situations, church, meetings, class, movies, plays, etc...I am always in the back half in the seat by the aisle. I can do public speaking again if I am in control of where I stand and have my exit strategy in place in my mind, if I need to get out I can step out for a moment, I am always by the door. I found that performing in my singing group really helped, these ladies knew my issues and they always just smiled and moved where ever I needed the group to stand, if I needed to walk away they just kept singing and when I came back they just moved a part a bit and I was back singing.
What I think helped most was the singing in the group to help me over come the anxiety. I had a well protected feeling and was able to stretch the wings a bit...If I failed it was no big deal.
What I'm trying to say is it made me get out of my comfort zone but in a somewhat safe way so could get stronger and eventually be able to do it without thinking my exit plans out over and over in preparation of going anywhere. The preparatory anxiety is the worst part of anxiety disorders.
Anxiety disorders can eat you alive and then you think about that verse in the Bible, Luke 21, about Men's hearts failing them out of fear...it took on new meaning to me. I just knew I was going to have a heart attack or something like that just from the fear of sitting at church on the bench that was 5 feet from the door instead of the one directly by the door.
If you don't get treatment for this anxiety, whether it be meds, therapy, counseling, etc...it won't go away for a long time and you CAN live better now if you treat this now. There are tons of anti anxiety meds out there and some are really good, they just keep you on an even keel and you don't feel like you've taken anything. Paxil is one of those, it made me itch all over but I took some others that were just as good.
Just know, you will feel normal again, it will take some time but it WILL come.
