over the last couple of weeks i have noticed that i am extremely tired...no matter how many hours sleep i get, im always feeling tired and dont have much energy at all. I have lost some of my concentration and have problems trying to focus for long periods of time. im also losing a lot of hair and suffering from bad mood swings, sometimes becoming quite violent. lastly, i have been bruising easily, and what would be a small bruise for someone else, my bruises are quite large and very dark and painful.
any suggestions on what to do or what the causes could be?
