More or less the same boat as you, OP. I'm just either better at dealing with it than I used to be, or simply going through a not-so-crap spell. No tips, really, ... experience, however, has taught me that it's much less likely to be something serious. Due to my anxiety, I went completely bald, ... yep, dude with lovely long hair (rocker style) and I went and chopped it ALL off. Hey, I completely love it, now. But I did that because I had spots, lumps, and pains on my head that were freaking me out in all sorts of unpleasant ways, so I got rid of all the hair so I could properly treat it. I now have a much nicer scalp, having treated it. It was just my scalp creating too much oil, ... that was it.

You're not alone.
