Hello,
I am so sorry that you've had so many problems for most of your life. I will say that I am learning a lot since having my anxiety and one thing is, you have to be good to yourself. Do know that anxiety won't kill you, it's just your body rebelling. I just finished reading a book that says when the feelings of panic start, just tell yourself ok, I can take it and face it. Sometimes we need to face our fears and boy having anxiety it's almost impossible to do that. When you have anxiety you want to stay away from situations that make you feel panicky and for me that's driving and just going out to run errands.
I will suggest trying some St. Johns Wort or Valerian. I would rather take something natural but I am on a prescription for my anxiety and I've been only needing it in the mornings. Also, is there someone you can talk to about your feelings? Sometimes talking about the things that bother you really helps.
I sure hope you can find a solution and coming here sure is a step in the right direction. Good luck and God bless.
Valerie
