Who should be my power of attorney?

My grown daughter and I are not getting along. I am getting up there in age. I currently have her as my POA if I ever need one. I am still with it and still employed. She won't talk to me or acknowledge my existence. She is my only child. Should I get a new POA? Who would that be? When she was talking to me she said she would still be my POA when I needed one. But if she hates me then I want to designate someone else but don't know who. Can't be a neighbor, my neighbors are all transients, they come and go, my pastor would say no and so would my friends, my sib would say no. Any suggestions?
