Depression and social anxiety ruined my youth. I've already made some improvements/mistakes trying to improve.

My current situation:

I'm early 20's, handsome and quite fit but badly out of shape (moobs, no definition), poor diet (working on it), dress badly due to shape, low pay job, no savings, no degree, unsure what I want to do career wise, a virgin, living at home, no driving license, a good talker but have a small social circle made up of awkward losers, no life experience (travelling, challenges etc), no hobbies, poor rep (people seem to expect me to still be depressed/ing).

I am going to improve my life and be better.

What would you do? Where would you start?
