Something I do when I start obsessing about something is tell someone or make a post here so that I get it from my head and get it out. Then I'll turn the radio on and sing along with as many songs as I can. If I'm not busy doing something, I'll read.

These suggestions are just to tide you over until you talk to your doctor. Best thing to do is to make sure of what it's not.

Take care and let us know how you'd doing, ok?
