my mother who is 88 yrs old cries all the time and gets mad at me a lot. she is really hard to deal with. i try to help her everyway i can but she seems like she's always mad at me. for instance she called me today crying that her cat was sick. all i told her i didn't know what was wrong i was not a vet she got mad and hung up on me. help as i am a only child and this situation is getting really unbearable.
