How can I survive my husband's Alzheimer's?

A fellow caregiver asked...

He is 76, hes had on set dementia since I married him at age 44. His doctor says he can tell he doesn't have Alzheimers after talking to him for 5 min. So he quit using his patches, he is deaf, refuses to wear his sate of the art hearing aids or his glasses. He really processes no instructons of any kind. I have no family to help me, His boys do not know, but never visit even so they do not observe. I am MAD, all the time, I don't want this burden. I can't do it.!!
