Medical mystery

It’s happening again, the brain fog and stuff. Like no amount of caffeine seems to help. I’m dizzy sometimes and it’s hard to even fucking talk. I feel so tired in my eyes, like sleepy. It always seems to happen at the worst times like driving or being in public. It’s scary as fuck and I can’t shake it. I know it’s not lack of sleep either because I went to bed early. I took all my meds this morning so it’s not that either.
