How to not get myself upset by neighbors once again?

I guess I just need to vent. I am trying to not get myself worked up, annoyed by my neighbors. These are the neighbors that my mother told lots of stories to about me abusing her etc last year. These are the neighbors that called the police that resulted in the great hooplah I have talked about before. Now that my mother is back at home after they wanted to put her in a nursing home and going to the day center, things have been somewhat been manageable, she realizes on some level what she did to create the crazy situation and she does not want to go in the nursing home. So, she has not been trying to wander out etc. Yesterday she came home from the senior center and told me the neighbors were there visiting her and wanted to know why she doesn't come over, this created a great stir in her. What the hell is wrong with them, they still do not believe she has dementia. It got me upset, and throwing in the towel crossed my mind. It is all about her and I am getting sick of it. These neighbors will not come over to the house, if they want her to go to their house they need to know that she must be supervised and if they want her to come to their house she will have to be picked up or taken and watched and then returned by someone. On one hand it would be nice to have someone help me with an occasional time out, but they do not recognize her disease and consequently foment discord and my mother gets nasty and tries to assert herself as though she is not well.
