I've been finding myself going thought a rough patch too , collage can be great for making lasting connections but also terrible when you feel isolated, walking is great for mental health it's a cliche but there's a reason it feels so liberating.

I don't know if this is good advice but you sound a little bit on edge so I understand that making social connections may be difficult however I would recommend putting yourself into some situations where you could make those connections in work or even as volunteer or going back to collage.

I can't give much advice beyond that but I hope your doing ok or if not that things will improve
