22 year old male. 6'3, 217 lbs, >20% body fat, mop of messy long hair, weak hairline, asymmetrical face, zero fashion sense. I don't take care of myself insofar as hygiene or grooming or apparel in large part because I have instinctively grown to believe in the last 3 years or so that I am going to be ugly no matter what I do. I'd like to be the guy who wears a nice shirt and shaves daily and always smells nice, but in recent months I've just found that so difficult.

I'm not depressed or anything like that. I just really hate the way I look and I feel like any step I take to mask ugliness is going to do nothing but lampshade it. If I wear better fitting clothing, it feels like everyone's just going to see that I'm actually fatter than I look under a hoodie. If I get a haircut and comb my hair, it feels like everyone's just gonna see that my temples are getting thinner.

How do I fix this?
