... If I'm 21 years old, will I die young due to this illness. My 21 year old daughter was diagnosed with Lupus a couple of months ago, she is very depressed because she has a 4 year child and she believes she will not live long to see him grow!! how true is this. please I am a very concerned mother, as she's always saying no matter what I will die young, she doesn't like to be reminded that she needs to change her life style. A Desperate Mom needs an answer!!! Thank You!
