This is might not be the greatest advice, but it's what I do. First, take a deep breath. Start trying to think positive. It's still early in the semester. Next, start making a list of everything you have to do for the up coming week. Prioritize it by due dates and how long it will take for you to work on it. Continue breathing. Next, sit down and tackle that first item on your list. Try to figure out what day you'll need to work on each item. For instance, if you have a long essay due on Friday, start it as early as possible. If you can write a rough draft on Sunday or Monday, with all of your ideas on it, not worrying about flow, or mechanical devices, etc, or anything like that. Try to take it to your professor or TA Tuesday or Wednesday (not only will you get some great help from them, they will see you are trying. They'll also get to know you more. The more they get to know you, the more supportive they can be when you need their help). Rework the essay, after you talk to them, and by the time Friday comes along, it's done.

This is my third attempt at college. The past two have gone horribly for reasons similar to yours. I'm finally doing well, and I"m really enjoying school. I know how hard it is to keep your emotions separate from your school work, but it's something you'll have to work on. Try to take little bites without getting too overwhelmed. Don't let your to-do list get you worked up -- only look at the things you need to get done that day.

Good luck!
