Hey man, remember that being "on the spectrum" in your case, or "bipolar" in my case does NOT mean there is anything wrong with either of us. It just means we are different than the rest, so we stand out. That's actually a good thing bro. Stars stand out, so do beautiful flowers. I wouldn't want to be like the rest of the masses, I mean, sure I would "fit in" better but I wouldn't have the personality that sets me apart. Same with you, I like you and what you have to say because it is different -- most people on here are saying the same shit all day, but you bring something different.
Lamborghinis and Ferraris are also different from "normal" cars, and they require different maintenance/care. But you don't hear anyone say that they are defective or have something wrong with them.
As far as drinking goes, you said you wished you could "drink a bottle of vodka and just chill". Have you considered marijuana? I don't know if it is legal where you live, so there's that. But I have found it to be a good alternative to alcohol. I don't use it every day, but on a weekly basis an edible really helps me find peace. It's a good way to "take a break" from life's stress in such a way that doesn't cause someone to become violent or feel like shit the next day. It's not for everyone, I'll give you that, but maybe food for thought?
Anyway, you did great by getting out of the house, and exercising was more positivity on top of it. Good job brother. That's the shit that needs to happen. Instead of "removing" alcohol, "replace" it.
Keep that ball rolling man, and stay positive. The pain is temporary, I promise you this
