Haven’t shaved in like a week, got a gnarly neckbeard growing: “Fuck this I’m so fucking gross and ugly why even both shaving I’ll just be disgusting to look at no matter what.”
After shaving: “Oh wow I guess I am kind of pretty and I look good when I take care of myself”
Proceed to not shave for another week. Rinse and repeat.
“I am insecure about being ugly, therefore I will master my ugliness by forcing myself to be ugly.”
I’m getting this from reading the wikipedia page on the compulsion to repeat so take it how you will. I may be in a similar situation to you.
