what happen to my super mom?

let me ask you guys something do you ever have a friend or family member that you think is just awesome & you think that nothing can go wrong but saddle reality has to give you a big slap in the face & that person ends up having something wrong with them like for my mom first it was told that slowly going to go blind now it's  arthritis in the hip & it hurt for her to walk & I hate seeing this becuz before all this happen she would do photography drive around & fine stores that soled cool stuff she never took crap from anyone like when my dad was still was marred to her he would go off telling her how she would sucked at this or how bad she was that & never got to her I mean there were times she would ask me if she was a bad mom but I would tell her to never listen on what he would have to say & unlike most women who cry over the littlest stupidest things if you knew my mom & when ever she would cry it would be shit hitting the fan like she can't paid the bills or something but knowing that it seem she trying to be strong but still to hear her said on why is life doing this to me it's almost like she given up witch kills me becuz she taught me to be brave no matter what I feel like i'm living in a nightmare & I just wanna wake up & wanted talk to some one about this but all they can say is that life get over it
