Isolation during autistic burnout: how do you manage?

I’m only now realizing what i’m going through is autistic burnout, most likely for years now but it keeps getting worse because I wasn’t aware it was happening.

Holding a conversation in any form, no matter how brief or who it’s with, is draining on a soul level. I miss my friends but I can’t keep up. I’ve let them know what’s going on but I still feel guilt.

What does your social battery look like during burnout?
