Dying of anemia, what?

Remember last post when I complained about how painful my runs have gotten?  And how I wasn't sure I was going to be able to run that half marathon I signed up for?  Turns out that I am not the loser that I thought I was.  I'm not out of shape.  I am severely anemic.  I had a full blood test last week and when the results came back, my doctor called me and started quizzing me all about bleeding - when I told him I have really heavy periods, he said, "call your OB/GYN, you need a hysterectomy."  Which scared me to death.  Anyway, after visiting various doctors, I am scheduled for an iron infusion tomorrow and uterine ablation surgery on Friday.  My doctor ordered me to stop running for at least a month.  I can't even run up my stairs.  The low hemoglobin really taxes your heart, and he said that I could pass out at any time.  Worst case scenario, heart attack.  Watch out for that anemia, its a doozy.  I just can't wait for everything to level out.  I want to feel good again.
