My family abandoned me after my divorce - my ex husband did some fucked up manipulative shit. (“I want us to be poly/for you sleep with another guy” -> “he cheated on me” when I finally did it to both of our entire extended families.)
What has helped me coped more than anything is new hobbies. Rebuilding a self. I started taking pottery classes and made some outside social connections. Art is a really good means of the self exploration that teaches you who you are and what it means to be a person again. Therapy of course, but you have to find someone that clicks with you.
It’s been about two and half years since it happened. (Well, the divorce itself was a nightmarish year long hell.) I’m finally starting to feel like myself again.
I’d say Google your local vo-tech or library. Show up to cooking classes or book clubs or something. Something new, that honors the new person you must become.
