SO glad you are getting on... The hemoglobin is likely the cause of your lack of energy and the fact that your body has been through a lot. It also effects your breathing as you know. You've been through a lot. I know you have no energy and it's cold in NYC right now, but bundle up and try a little walk - it may help just a change of scenery and to stimulate your metabolism. Do you have someone you could walk with? Just a block even. It would help with O2 exchange. Though I suspect you may have to wait for your hem to get up a bit more to feel better. It does effect your healing so maybe talk to them about a transfusion? Also your diabetes issues do have bearing but you know all this.

I'n not surprised after having more rads your skin is having a bit more trouble this time around. You've cooked it a few times. Again I am sure none of this is new to you. Do they have you on iron?

Hopefully you heal and then get back to almost normal. Hugs.
