Hi Docter, I m a 26 years old, but I feel like I m 70. I can t seem to keep nothing in mind, don t have any short-term memory or whatsoever. My mind is very chaotic (always has been), can t seem to concetrate on anything which is affecting my work and studies. I had a blood test last year as I was experiencing tiredness all the time, but it didn t show anything in the results. I never wake up feeling fresh, even if I sleep 10 hours or so. And last when I walked home I couln t keep my balance and was about to hit the ground, like I was drunk (I don t drink alcohol). I almost walked into a car! This lasted about a few minutes. My mother died of cancer and my father died of a heart attack, I m afraid maybe that s the reason I never feel OK?
