19 and taking a gap year rn.

I'm working out and have some hobbies enjoy.

I just started this job at buffalo wild wings as a cashier and I feel myself being super awkward. At the gym when I talk to people I feel super awkward. At my MMA gym it's the same thing.

My confidence is kind of shot because I got cheated on 5 months ago (before I started the RP journey).

How do I become more confident? I feel good about my body and looks. I like the direction my life is going in - but socially I'm practically retarded. I want to approach chicks (not that many to, but whatever) and meet new people - as soon as I get into a conversation I lock up like a sperg.

Any advice?
