I've been having a headache for the past 2 months everyday in the morning at around 04:00, i tried grandpa which sometimes it doesn't help. i hardly sleep enough?

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Wish you good health!
