I'm an 18 yo female. I've been diagnosed with depression, and generalized anxiety disorder. For the past, i'd say, abotu 6 months, I've been experiencing on and off an annoying and scary sort of brain fog. This is the only way I can describe it. It's almost as if i'm living in some type of dream world, and everything is super unreal. It waxes and wanes. I went to the doctor at a time it was really bad, and he brushed it off as sinuses and gave me some zyrtec. Needless to say, it didn't help. I've had cat scans of my sinuses and they're totally fine. Lately, i've been really dizzy all the time. And i've experienced episodes of vertigo, where it feels like the floor drops,and nausea that accompanies it, but the nausea is not very often, only once or twice. I've always had problems with getting up too fast, and sometimes out of nowhere, my head will start to get tingling sensations. And when I close my eyes sitting up, like when i'm in class, everything seems to be spinning, and I'll get that falling sensation that people get as they're drifting off to sleep. I don't know if all of this is due to my anxiety, but i'm taking medicine for it, so I feel like it shouldn't be. I am overly concerned with my health, but I just can't help but feel that there is something actually wrong with me. My mother has MS, and I know that these can be signs of MS, or at the very least, a neurological problem. But, then again, I did have surgery on my ear when I was younger, so i'm thinking it may be vestibular as well. I'm scareeeeeeeeeeeeddddddd.
