I Am Very, Very Dizzy, Light-headed, Carrying Something As Simple

I am very, very dizzy, light-headed, carrying something as simple as a laundry basket up the stairs makes me feel like I am going to black out. I can't stand in one spot with out having to take a step forward or back, as to not fall over. Bending over to set something down, I feel like I'm losing my balance and faceplant into the wall. Tired all the time, no stamina. I just feel weird.
