Suggest Treatment For Frequent Headaches

Female, 18 years old, 5'3", 115lbs. I have been having frequent headaches. They come daily, lasting a number of hours at a time. The pain is shallow and constant, located mostly in my forehead, though it feels pretty evenly distibuted throughout my head. In addition, I've been feeling unusually drowzy through out the day. Even with a nap I will feel out of it or disconnected during the day. I was taking meds for anxitey and depression but stopped recently, at least on a daily basis. Could this head pain and fatigue be connected to the medicine lacking in my body, or are these symptoms of something else that I should consult my doctor about?
