Brain Fog

i find daily that my cognitive abilities worsen. My word finding and short-term memory have noticeably changed for the worse as well as when i am typing i am continually inverting my letters as if i were dyslexic. It is very frustrating and demoralizing. i have a difficult time retaining what i read and doing things like my scuba diving class reading takes me like three or more hours where for the normal person two hours. When i am finished i am not even likely to be able to tell you what i just read! i feel like such a FREAK of nature! The BRAIN FOG is not physically painful to my brain but is painful to my soul, my energy, and my self-esteem.
