Were you a subreddit mod? In this case my advice would be to contact the existing mods of the lemmy communities / kbin magazines and see if one of them is willing to hand the community over to you (add you as mod, they step down). If so, you've found your new home!
(you may want to re-make your account on the instance that you're primarily spending time on, for convenience, in case federation doesn't work for several hours at a time here and there, etc)
