CherylC gives some good advice. I don't want to steal her credit
You are very young and it isn't clear yet that you even have MDS. The average person with MDS is 70+, so that will affect the life expectancy stats as well.
Focus on the positive and the things that you can control - like no smoking
If ever there was a reason to quit, this would be it!
My doctors also told me to eat a varied diet that included meat. So, I will just throw that out there as well.
I hope your next CBC is headed in the right direction. Sometimes the marrow can heal on its own if the cause of the aplastic crisis was a drug or chemical exposure that has since been removed. Youth is in your favor!
Best of luck!
