I have been suffering from lack of interest in almost all the activities which use to be the interesting and favourite activities before . I like to be alone now a days by just sitting simply and doing nothing. Also have trouble concentrating while studying and in classes. I loose interest very soon while studying. I also have excessive sleepiness that i cant get up in the morning. I do get headche few times if i sleep for more tgan 10hrs and if dont sleep 10hrs then i will be drowsy all day
