How can I overcome my hypochondriacizm

[Tastee]

I'm an extreme hypochondriac.

I constantly fear all day that I'm going to get cancer from eating meat, or get HIV from common contact with humans.

Example: Today at K-mart the female at the counter scratched me on accident.

If you understand how I feel, then you may know how this triggered my terrible thoughts.

I immediately started to think my life was over, that's it, I have HIV.
I went right to my bed and sat there for two hours just depressed and upset with how my life is now ruined from getting my new rug bagged by this woman ( that's when she scratched me, while I was assisting her put my new rug in a big bag)

It hurts. I have an issue living like this. I will never take any medication for this because I can't put pills into my body..

Trust me I know people have bigger issues out there and I'm not trying to seem like im so important, but this really affects me. It changes who I am. One minute im happy go-lucky.. then the next im in fear..

How do I over come this? I need some sort of reassurance that I can't get HIV this way.. and that there's hope..

thanks for all who show sympathy.

much love
