hi, Im 17 years old. Ive been having headaches everyday now. im always tired. Even sleeping for a long period of time, i still am tired. when I am outside in the sun, i get headaches located by the forehead area. I cant stand listenting to music sometimes. also, when I try to study, I start getting headaches. Another is that, I feel like im forgetting a lot of things...I used to be so good in class and study very well on test and quizzes..and it seems like now I dont remember half the things i studied. I accidently hit my head on the wall (my left side of the head) really hard, but i felt fine after that... this happened on Christmas, 3 months ago. Please help me out, I just want to know if I am alright. and if i am diagnosed with anything, i dont want to visit a doctor because i dont want to worry my parents.
