I'm excluded from one of my only friend circles and now I feel alone again

One of my online friend groups is giving me the silent treatment. None of them are responding to my DM's. I distanced myself from them earlier this month because I felt like I didn't really fit in with them. I got lonely so I tried coming back, but no reply. It seems they want nothing to do with me. I feel bad now since they were some of my very few social contacts, even if they were kinda toxic (which is why I wanted to distance myself from them in the first place). I transferred to a new college and I've been having a rough time, and losing them is just making it worse.

I feel like even if they were toxic, at least they were something. I'm getting busy with college, and I'm too drained to pursue any social activities. Even going to class and being around others in that capacity exhausts me, yet I still crave someone to talk to. I feel like there's no one I can really relate to, not my roommates, not anyone. I feel like I lack anything to truly offer to anyone, and it's no wonder, given how it seems I can barely keep myself afloat. Somehow, I managed to get that friend group, but I wasn't happy. I didn't feel like I belonged. And now it seems whatever I did irreparably burned that bridge, and I'm starting from zero. I don't know what to do with myself. Sorry if this post is a bit aimless, it's hard to put my emotional pain into words.
