How do i feel less self conscious?

Just walk around like a boss. Self consciousness should come from how you feel not how you look. If you're short and fat so be it, but at least you know your flaws and you're funny. Puffy , jenny craig, skinny from front but from the side you look fat. You're obviously a funny dude. Build on a good personality and go from there. If you fat or ugly or whatever the case may be, people will still like you if you're a good person.
