you just have to let your mind over ride it...knowing from your past history that it is just anxiety causing the stomach problems and that you are going to be ok and that you are just going to have to ride it out and go to work. my anxiety causes chest pain, sometimes so bad I am certain I am having a heart attack. I know that if I were having a heart attack, I would be dead by now. so I just ride it out, knowing I have never had a heart attack from it, that it is only anxiety. sometimes it lasts for days. I just keep doing what I have to do and ignore it and eventually it goes away. I wouldn't have a job either if I let anxiety run my life. take care.
