Roomate found my meds and made fun of me

Freshman in college. Just came back from winter break a couple weeks ago. My roommate has always been a bit mean. In fact, from coming to college in August, i have worn a hat literally every day. Hopped on my meds in November, and I've seen some good progress. Coming back from winter break, I ditched the hat for the first time. Felt pretty good.... until I was hanging with my roomate and other people on my hall. Literally all 3 of them roasted my hair cut. Only one dude was nice. Anyway... my roomate was the main guy making fun of my hair and calling it super thin. I kinda just laughed and kept quiet the entire time. That night, he went through my desk drawers and found my hair meds. Now he's been telling everyone I'm on drugs. Not really sure what to do because I'm not confrontational. I kinda want to just room alone next year....

TLDR: mean roomate telling everyone about my hair loss meds, I'm embarrassed a lil
