Light Body Experiences - Exhaustion and Forgetfulness

i don't know how to explain this but i'm tired all the time overwhelmed in body and spirit, my hair and nails are a problems either falling out or breaking splitting and don't grow, sometimes i feel a calmness i can't explain and the other times i get stressed beyond words, i don't take drugs or liquor i don't go to the doctor and take their pharm drugs, i don't get enough quality sleep and it gives me brain fog, i'm very forgetful of late, more than usual. i just have this overwhelming tiredness i can't explain. it affects my whole spiritual and physical well being.
