I am 5'5'' and 108 lbs, have been feeling tired and weak, is there a way to tell if i'm anemic without seeing a doctor?

TIRED & WEAK.: I'm a dr & i don't know enough for an honest answer - you didnt give enough information. Sometimes people are afraid of drs for fear of the dr disapproving or the need to say something theyre ashamed of. Go to a dr who can think with you enough to know the direction to investigate. No one will take blood without your permission. Courage!
