Hello iheartu,
I know I hate it when people say "you have to go the doc." but, its the only way you can find out for sure what's really wrong. Having HA everyday is NOT normal,

I know because I had them, and I know how being in school with a headache can be!
What do you take for the headache?? I used to take excedrine for migraines. and even now i keep taking them since i can't take the imitrex that the doc prescribed.
Anyways, I guess your best bet is to go to the doc, and they'll run a series of tests to see if there's nothing serious, and then they'll give a diagnose. At least that happened with me. But hey, do try get checked. Sorry if didnt helped much.
