As the title suggests, every time I find a random lump or bump somewhere on my body, I freak out to the point where I'm basically convincing myself I have some uncurable form of cancer or another terminal disease. Today it was a bump on the roof of my mouth which returned after I had it last year. I even got it checked out by my GP last time and she wasn't worried in the slightest. 

I've been googling for oral cancer symptoms these last few hours and obsessively checking my mouth in the mirror with my phone's flashlight on. I'm so sick of living this way and I really want to learn to live with the uncertainty of being okay with whatever happens because I have no real control over it anyways. Ofcourse if something really seems off, I'll have it checked out, but god all the worrying is really taking it's toll on me.

Any tips on how to deal with this are greatly appreciated.
