I have my exams coming up, have studied nothing. there are a lot many things going on inside my head which is giving me major headache and my entire body is in pain. I want to study but I keep on thinking about other things. I don't have any friends for a while now. the ones I become friends with things eventually mess up. it's very difficult for me to maintain friendships and am feeling lonely most of the times therefore I prefer sleeping all day instead of studying. pls suggest what should I do I have got a lot to cover
