Is ther there any hypochondriac here?

Hypochondriasis (or hypochondria, sometimes referred to as health phobia) refers to an excessive preoccupation or worry about having a serious illness.

I worry so much about my health. For example, a friend having a bite from my pie, id think id get sick because that person is sick. If i feel something I go online and research for that and seriously worsens my condition.

The only and last time i cheated on my gf, and thought id get something. I was feeling sick and all maybe because of the guilt, but the results was all good. And when i got the results all I was feeling went away.It is really amazing how mind can play some tricks on you.

Is there anyone like me? How do you “lessen” or control this things..

I found some sites but it would be really nice to hear from real people and whatever you think.
