I'm 18
Very shy with girls, have no confidence at all, settle to get laid :/.
I use to be heavy into drugs and drinking and changing my life so i'm not hanging out with a lot of the old people I was so I really don't have that many friends anymore, so going out with friends/wingman really doesn't happen cause either no one to go with or I get flaked

Personalities are transient, you can mould yours into whatever you want.
Life is a game, its all about acting really on the face of it.
You have showed signs of a above normal will power, by leaving your old friends behind and leaving the substance abuse behind, so keep with it. Get a new style you like, start up some new hobbies, martial arts, dancing, music, get friends from these new circles. Maybe start travelling, reinvent yourself its fun. Confidence is all an act, the more you socialise the more confident you are, if i don't socialise for a while, i tend to come across as shy, if i do socialise often, i become a pro at it.
