Suggest Remedy For Constant Headaches

i am 18 years old currently and ive had headaches since i was in 5th grade on and off. i am constantly tired and lately ive had migranes non stop and get dizzy. when i excersice i see black and my eyesight gets blurry. in 9th grade i was told i had a cyst in my brain, he wasnt a brain doctor so he said i should see a neurologist but we were rescheduled 3 times so my mother gave up. its hard for me to enjoy everyday activities because im not sure that i sleep at all at night and like i said i have constant headaches. could the cyst be the cause and if so should i get it checked. thanku
