Iam really depressed and dont know what to do. ?

You are caught in a circle. Have you thought about a suicide hot line? They could talk to you about your struggle. It might help. It sounds like you are trying to have a regular life, but with all that is going on in your life I'm sure it is difficult. Can you go to your parents or friend? If you go to the clinic they can give you some medication to help you. Good luck
