I feel completely and utterly alone.

I posted before on this subreddit abt how I fcked over my life. But right now its just a life update? School just started, and I have 0 friends as of right now. My ex who dumped me is in the same club, so I can't go back to that. It was a huge source of social support for me, and having that taken away makes me feel very lost. Everyday I go to school, find some remote corner to do work, and when I start feeling the sadness come I get up and go for a walk or get some coffee. And once I'm tired of doing work I just head back home. It sounds really miserable, and I want to make new friends, but because of the depression as well I'm not as sociable as before.
