Yup, AML sucks. My mother was diagnosed with APML in April 2011, which is a variant of AML with a much better prognosis (more like 90% than 50%). I was so relieved when we found out it wasn't AML proper and she wouldn't need a transplant, but it did get me to finally sign up for bethematch.org. Not everyone is "lucky" enough to get APML.
Those first couple weeks I was pretty sad and felt sorry for myself a lot. When friends started organizing drives I got totally immersed in helping to organize those and forgot about everything else. When that trailed off, I guess I'd come to terms with it. I wish I knew exactly how long I had, but nobody ever does.
I'm looking forward to using this as an excuse to do a lot of things I'd been putting off and living the life today that I always figured I'd love someday.
