My family's cut me off, I just had a mental breakdown about a week ago, and I have no idea what to do. They thought that I haven't been going to class, but when I had the breakdown I had to drop my classes so that I wouldn't fail them, but they don't understand that. So...
Well the title of your thread certainly sums it up pretty well.
I think we all need more details to respond to you in any meaningful way though.
Do you have a job?
Friends? Any of whom you could stay with?
What kinds of interests do you have?
What would you be willing to do to get your life going in a more positive direction?
Are there any opportunities available to you that could be helpful, that maybe you've been thinking over?
Also, of course, feel free to add in any other details you think might help us understand your problem better so as to be able to offer you something more beneficial.
