Exposure therapy. Volunteer. Take a class. Force yourself into a social situation you're obligated to. It will suck at first if you're awkward but it gets better and easier the more you do it. I used to have borderline panic attacks talking to people after a year of being unemployed. I joined a CrossFit class at my gym and you're forced to have a group of four. It was brutal because I was one of the only guys there, but every day it became easier and I actually look forward to it now. I even met my girlfriend there all because she complimented me on my Lana del Rey tanktop lmao. Also quit watching porn (or watch it less frequently) for a while and see if it makes you less awkward. That turned out to be my main underlying issue.
