When I went on suboxone my anxiety went to astronomical levels. It's a partial agonist and doesn't cover up anxiety and depression issues as a full agonist like methadone might but I can say I went through something similar to yourself. If you have old friends that you know and trust that aren't into the drugs you were addicted to, practice socializing with them. Push yourself to go to recovery meetings, make an attempt at speaking and telling peopke what you are going through. Even if you start having an anxiety attack and crying just sit with it. Sit with it and feel it and confront it. It's exposure therapy, I can guarantee that someone there will empathize with you and try to talk to you, just keep trying even if you are incredibly awkward and struggle. The more you expose yourself to this irrational fear, the more awkward and perceived humiliating experiences you have, the stronger you will become because even after the most awkward of experiences, the next one couldn't possibly be more awkward. Just stick with it and don't hide, keep going and trying and staying and showing yourself that it isn't that bad and the way you perceive others as judging you and looking down on you is mostly you projecting your own insecurities.
There are assholes out there but they are usually just projecting their own insecurities on you and you can't own that. Accept it for what it is and don't let assholes get you down. I tried and struggled these past 4 months, I was let down by everyone I trusted when I was begging them for help but they don't have to care and I adapted on my own and I have made progress and I am not afraid anymore. I really wish you luck and I hope you realize that you do have the strength and courage to not isolate and hide and to expose yourself to the most awkward and uncomfortable situations and make it through. You really do have to fight the uncomfortable feelings and not wallow in self pity or run away and isolate. You can absolutely do this.
