I am sorry you are feeling so down Rift. For me, just getting out helps. The four walls can close in quickly on me if I let them. I know you mentioned having difficulty dealing w/people right now. What about volunteering at an animal shelter? We have the Guide Dogs training facility here and folks go and walk them, deal with the puppies, etc. Something along those lines really gives alot of people meaning because there are so many organizations that cannot function at all without volunteers, so it's not fluff...it's giving of yourself in a meaningful way that has a huge impact. That's just one idea but there are many organizations that need help and where you wouldn't have to deal too directly with people if you didn't want to. You have talents and gifts that others need whether you see them right now or not...
The good thing is you said your sobriety matters to you
I hope you feel better soon.
