anemia tips?

The last couple of days I've been having really bad side effects of anemia due to low hemoglobin (not iron) because of chemo. Regardless, the side effects are really bad. I'm always cold (which isn't normal for me), I get short of breath just from walking, I feel like I can't breathe at random times and my heart will start beating really fast. Also, my bf told me I look really pale. I know my side effects will wear off eventually but anyone have any tips on how to manage it in the meantime? It really sucks. I've been in bed all day and I still feel so tired.
