What is wrong with me? Can anyone help?

For the past few months, I've really slowed down. I used to always get so much homework done every день in no time at all. I used to get a drawing done every two days like clockwork, like a manic machine. But now i might get a drawing done every week или two (and i effing Любовь drawing). And i sometimes go entire weeks without doing homework. I go to a class were it's only a few hours a день 4 days a week and most of the work is homework, so that is a big problem. I just spend so much of my free time doing stupid idle shit that i don't care about and can't stop.
I was homeless from March to August and allot of fucked up stuff happened, but i don't think that has anything to do with it, but it's only started happening since i came home.
It just seemed like time was going by too fast, but now it just all seems so slow. What's the problem and how can i regain my old productivity?
