most of these symptoms are text book ocd.
My thing was around 23-24 I was obsessed with loosing my hair. I thought I was going bald and I would look at my scalp constantly, 20-30 times a day and it would aggravte me that my hair got in the way of me looking for potential balding areas. Thankfully, I was in school at the time and was aware of the problem and it's treatment. I went on xffexor and clonopin and it kicked it all in 6 weeks. It's been about 7 years and I still have tons of hair and could careless if it falls out
