Hey man, I can certainly feel you on this front. I am in a similar situation, having dropped out of school, then lost my love, then lost a job. I felt at school for a long time like I was just lazy, or didn't care, and that everything was simple. But I couldn't bring myself to have any motivation to do much of anything, and it all slipped away. I've just recently sought help from a psychiatrist and he's got me on meds now, so hopefully you can seek some help too. You can't get better if you don't look for help.

Best wishes mate
