Family: you're out of shape
Google: anemia
Me: anemia, EZPZ just see the doc and get some iron pills, right as rain

Hey no worries, that was back in 2020, I'm now almost a year out from stem cell transplant. Lucky for me I have a brother that was a perfect match.
I appreciate the thought though
Edit: I understand that many people aren't as lucky an I was, so I want to encourage everyone to register to be a stem cell or marrow donor if you can. Also donate blood (if you can), I needed a LOT of blood transfusions through the course of my treatment
