How do I confidence? [ Slightly Rambly, Need Advice ]

Okay so couple of quick things to catch ya up on why I don't have alot of confidence in the first place. Im slightly on the spectrum, -So alot of the little neuonces fly right over my head. Between the anxiety of causing a fopa and the embaressment of shoving my foot in my mouth or rambling, being social is just harder.I wasnt raised with pride. I was raised her under her boot. -Be it being okay with my sexuality, the A i got on the test, the double I hit in baseball or whatever i achieved, was, or could be really didnt matter. For many years i was simply just a living subscription service to clean, care for, and be abused by my mother. Building confidence and pride wasn't on the agenda. (We are trying to fix our relationship and she has appologized since)School was hell and made me really jaded towards the intentions of others. -self explanatory. Although I continue to work on this, it makes it really hard to want to go out and interact with people in the first place when I feel people are judging me negatively or simply just taking pity on me. Things Im attempting to change/doing to help with that. My health in general. Went vegan and I'm working off alot of weight. I started at 330 and im below 280 now.General exposure, Im hoping that by simply being around more people that I'll just get better at being human and that ill simply get more confident through repeated exposure and reassurence im not some bubbling idiot. Any suggestions or should i just keep plugging away.
