A 0.9? Are you even going to class? That is the total key to getting a passing grade, because professors will give you the benefit of the doubt if you show up. Also, I found that simply going to office hours to talk to a professor can turn an F into a passing grade.
College is tough as is, but more when you have depression. Talk to somebody about it face-to-face – especially a doc who can give you pills that help it A F-LOAD. And browse around online – I think the turning point for me was finding the book Painfully Shy at the library a couple years ago.
Do something different. Get up. I realize sleep sounds spectacular, and it always does for me. But get up, and go do something – even if it’s just to get out of the dorm room to walk around campus. It helps more than anything, if you can make a habit of leaving and moving around. Out of the blue I decided to start running, which has made all the difference.
I was the most depressed at the start of college. Not sure why, but I look back and somehow miss those times, just because that’s when I still had a choice. Life was still open, and that’s when it got shaped.
The problems you’re talking about, talk about them more to somebody you trust… obviously not your peers or parents if you can avoid it. Here is good, as is a doctor. But you have to try to put those problems in some sort of order, or you can never ever hope to put them to rest.
