Your best skill for right now should be survival. Being out of shape is bad enough on its own, but paired with a mental apathy it's a death sentence. People like that die when they're 30 and don't get buried until they're 70.

Eat better (and less), run more, lift more, lose weight, feel better about yourself, get a new and better job, attend more events, read some books, cut out media you don't need (video games, youtube, whatever), and you can grow into the organization with skills you pick up.
