I'm stuck, in a hole and I can't get out. I'm a 21 year old college student and completely miserable.?

Im in High School but, I understand that you are getting stressed out, try not to let things bother you as much. And although it it tough on you still atleast try to communicate with other people and don't cut off the world completely. Depression is very common, but remember that although it feels like the end of the world it isn't and there is still Happiness waiting for you.
