Hello, suman111, and welcome to Psych Central! I am wondering if you might be having some depression. Is there anybody at your school you can talk to? Of course, I guess you will be away from school for awhile, assuming you are taking final exams.
Are you not interested in what you are studying? Are you excited about your major? (I am assuming you are a college student.) Often once students decide what they want to do and are really are looking forward to it, then they feel more motivated.
Hang in here. Let's see what other folks say. Again, welcome!
