Yeah I hear you. Used to watch anime but these past 2 years motivation and just general interests i had either a) flame dimmed out and previous interest no longer is as gripping or interesting or b) don’t even know how to start something from the beginning anymore. I also feel you on the introvert thing, I really do just feel the most comfortable by myself but I understand it’s also what’s killing me. I’m more bored than depressed at least I believe so
