Muscles burn, bad memory, malabsorption.

These are some stuff i identified in my symptons, also, I'm not on any medication nor wear glasses. Blurred vision. Tinnitus. Brain fog. I've insecurity, and bad memory recall plus hard time memorizing long texts and sometimes I get in loops to memorize a phrase. Some sort of fibromyalgia: burning feel in the muscles since I was 8 years old (tiggling? I tend to contract muscles to aliviate the feels, but now I do contractions less often even though the tension is still the same and now I feel them on the temple which I didn't before for as long as I remember.). I have D vitamin deficiency due to malabaorption I believe, which comes from a folic acid deficiency. I have some light symptons of aphasia connected to speech cluttering and prosodic patterns and thought disorder, which lead to distraction and focusing problems.It seems that I live like if time doesn't exist even though I try to be on and in time when I have to. I study a lot but I'm sensible, but I doubt a lot.
