im sorry you feel so lonely, as for the school thing you can buy books my brother is doing that to study for his g.e.d test there are also classes if youre up for them, i say work on your education first if possible, i also suggest doing something fun and if you find something youre interested in, that can be a conversation starter,even a little interaction is good you know, you can start out small by maybe saying good morning to neighbors, then work up to small conversations maybe a how was your day or something , i know you can do it

. i wish you the best of luck and im here if you ever want to talk.
