in the last 4 months ive had 6 "spells" that get worse every time. there is no common trigger and i have an appointment for an MRI tomorrow but i want to ask what it can be. last night was the worst so far, the time before i fainted 2 times with no memory of even "falling alseep" i had some friends over and got hit with an intense headache last night and had sever dizzy spells and was extremely nauseated. i was shaking uncontrollably and apparently started crying because i was in so much pain. i vomited 2 times and my friend continued to give me water with electrolytes to keep my hydrated. i started having what my friends described as "geek out" sessions where i started laughing hysterically at literally nothing.  right now my headache mostly subsided but my nausea is just as bad. my words were slurred last night and i was very confused. i eventually could concentrate on a conversation after a few hours (my friends kept me awake and tried to keep me in a conversation until my head felt better) i was very forgetful, if i were to read something literally right after i read it i forgot what it was and i spaced out in the middle of conversations.   i was also extremely paranoid and  refused to let them take me to the hospital i wanted to just stay in my home. i tried to look up my symptoms but there are so many things that they encompass i started getting paranoid about the 1000 things i could have. if anyone has information it would be greatly appreciated. thank you.
