dying...slowly..or not so slowly

i literally feel like i'm dying. or at least close.
i haven't had super bad headaches in a long time. but when i had my last 2 horrible ones, i took excedrin. which has caffeine (which never causes problems) tylenol ( which also never causes problems) and asprin (which i never take). and it always gave me horrible stomach aches.
but this week in lab we made aspirin. i didn't even think about it, but after we made it i was rly tired, and when i got home i took a nap. when i woke up i was ridiculously dizzy, and felt like i was gunna pass out. and i've felt like that ever since. my mom thinks maybe i'm allergic to salicylates (def: A salt or ester of salicylic acid, containing the group C7H5O3.) because thats basically what aspirin is. so since wednesday afternoon i stopped eating foods with salicylates. or as much as i can. they're seriously in everything!! i can have meat, cheese, bananas, eggs ( i think) and a few other things. but anyways.
the dizzyness hasn't stopped. idk how to describe it, cuz dizzyness isn't the right word. but my brain isn't able to concentrate and figure stuf out. i'm making weird mistakes and i can't type. which seems like a small thing, but i've always been able to type. i have to concentrate super hard to make sure i'm saying or typing the right thing. and i feel like if i stand up i'm gunna fall. time is all screwed up, so it feels like i've been typing this forever when really its been like 5 mins. and its scaring me
i don't know whats causing it. its not the extreme change in diet, cuz it started before that. it could be the vitamin d deficiency, but i've been taking a ton of that. its just weird. and doesn't make sense. but i'm gunna call my doc or have my mom call him and see if he has any clue as to whats going on. its seriously freaking me out.
