A lot of these symptoms sounds like neurological or psychological issues. With the racing heart and dizziness and fatigue, it could be anxiety, and the ear sound could be tinnitus, but it's really difficult to say one way or another because there are just so many different types of symptoms. The face-blindness and speaking/singing to oneself reminds me of my father, who is in the middle stages of Lewy body dementia and also has dealt with anxiety and depression for many years. However, some of these symptoms could be side effects of drugs. Do you currently take any medications or street drugs?
You should probably see a psychologist and maybe even a neurologist if these symptoms continue.
Oh and also i forgot to mention when its quet i can hear a sound coming from my brain its like bee sound in my head or my ears
