i do that kind of stuff all the time! Except mine is I have had blood tests upon blood test thinking they were going to find something horrible but I was fine. Also I have had my heart checked for abnomalaties(although I am only 28) and a cat scan. All because I thought I had cancer or something bad. But I was fine. It don't matter though I still obsess about my health and it causes me alot of anxiety. It's all I think about. I hope you get better cause I know how this kind of thing is.You're ok though. And welcome to psychcenteral
