Why me

Can't sleep sitting watching tv thats what older people do.  I should be strong so i can work that one reason my husband left me tired of taking care of me .then ran into an old flame of mine had my stroke he left because i didn't want to have sex.what good am i i cant stand to long my legs hurt .i cant even work part time cant stand to long. Life suck i shouldn't fuss though I'm still alive i ask God why he told me you can help others who hearts that hurt. Then i will feel better about myself.it not good to complain just find your friend and enjoy the golden years.
