medical marijuana qualification?

OK. i am 16 years old. i live in Spokane Washington and i suffer from something that no doctor has been able to figure out. i don't know what causes it but i get this horrible pain just behind my eye. its not a migraine headache though. they start out as kind of a dimming in the effected eye. s in everything in said eye look about 60% darker. then in less than 5 minutes that whole side of my head starts to ache in such a way that i cant move. i cant keep my eyes ope. i have extreme sensitivity to light sound touch and even movement. then i vomit. this pain can last anywhere from 10 minutes.. to a maximum thus far of 36 hours. i do gain mobility after 30 - 40 minutes although it is highly uncoordinated. i realized 4 years ago that marijuana not only relieved the pain almost instantly but also left me feeling cheerful longer. (i have also been diagnosed as manically depressed and have tried other medications which either made me feel psychotic and almost skitsofrantic or a brief bout of cheerfulness fallowed by extreme mood swings and in 2 cases vomiting) i need to know if i can qualify for a medical cannabis license because these pains are becoming more violent and more frequently. please help me.
