I think I might have anemia because: I ve been feeling dizzy and light headed when I stand up; for about four days I didn t feel hunger at all and so went without eating; I get easily tired; my joints and arm just start hurting randomly; every so often I get a tingling sensation in my hands and I have to itch them to stop; I go from having lots of energy and euphoria to being weak and angry for no reason; and I ve started dry retching now over certain smells like: if I m chewing gum, I feel like I m about to be sick and have to get rid of the chewing gum as soon as possible and someone had cooked stew for tea and I had to go outside to stop myself from retching over the smell. Also, the smell of Ferbreze makes me choke and feel sick. I can t go into the toilet after someone else because I m so sensitive to the smells. I always retch when cleaning my teeth.
