Yo, I have had trichtilliomania for 5 years. I pull out my eyelashes and some hairs on my body. I dunno about you but when I get anxious I get this sensation to pull at my hair and it feels better :/ have you tried Prozac? (Fluoxetine)
It hasn’t really helped me much besides made me feel less anxious. Just try and think your hair won’t grow back LOLLLLL
