Nocturian

When I was little, I got migraines so bad that I would throw up and choke on air. I know exactly how you feel. 

But the thing is that i don't even know how i can overcome it, all i know is that my brain is behind this

Hmm, I personally think you should get a brain scan. The doctors might find something that is causing the pain. Its a bit pricey depending where you live but its worth it. Finding ANY solution to your kind of situation is important.
