After 3am from coming from college exams are going on I felt sleepy and then slept But restlessness occoured and waking up feeling weak and sleepy Yesterday I didn't got proper sleep I was revising my syllabus and got sleep by 11:30 pm but slept at 1 am approx due to restlessness And wake up at 5 am to study and after hectic schedule of exam I am feeling bad now. There is a pimple on my finger I think filled with water due to that I couldnt write properly too Should I take any medicine And how to sleep correctly and release stress.
