My mom was just diagnosed at 78. It came on so fast. She was so active. She cant have treatment because she developed pneumonia. I have seen so many sick children and young parents and yet i feel like my mom is not too old to live. I want her with me. I see these others and i feel so bad because i have had mine for my 48 years and she has lived a full life but its still not enough for me.i cant imagine life without her around.i will pray for you and your dad.
