Unless you have a work from home job, I don't think think there's something exactly like what you're looking for.

Most would require some kind of substance problem or criminal problem. Options that don't wouldn't be full time stays, or would be vacations/not working.

Your best bet would probably be to join a club. Like taking a class at the YMCA, or signing on with a D&D team at the local card shop, book club at the library, etc.

Its not a full time situation like you want but it would be something with some structure and socializing you do weekly. And they're low stakes, things people shouldn't care about if you get nervous and don't show up.

If you have the money to spare, you could also stay at a local hotel for a while. It would give you the feeling of getting away for a while, but also keep you in range of getting to work.
