Does my mom have any rights after the court gets involved and she now has dementia?

My mom has dementia since June. She didn't want anything to do with her kids for 7 years. They did some bad things to her that caused her to loose her home and loose her marriage to my father of 45 years. (my father not theirs)They also had me loose my home where my mom lived after she lost her home. They have stolen from her at my eviction. They moved her things outside to get wet and was laughing about it. My mom was in shock to watch what her own kids were doing to her. My mom and I put all our things into storage which we have shared for 7 years. Her name is on it and she paid most of it as that is what she wanted and what we agreed on. She also wanted to live with my daughters and I. We have been together for 7 years. I have been taking care of her. Her kids found out where we were and came into the house and took her by force without me knowing. Now it is going to court and the court ordered a guardian ad litem. The court allowed her to stay with one of her granddaughters she hardly knew and before she got dementia didn't want anything to do with either. Now my moms dementia got worst since she was kidnapped. The court won't let her come back to me because her kids again made up lies so the court is going to put her into a home. Something she never wanted. My mom gets $4,000 a month. The guardian wants to sell everything of my moms in the storage, including all my things. The guardian says if there are receipts from the past to show my mom bought things for us as gifts we have to give back so the guardian can sell it. I am not allowed to go in and get any of my belongings. Because her kids say there is nothing in the storage that is mine. Therefore I have to prove with receipts. Who keeps receipts for everything they buy all their life? I know for a fact that my mom would not want her things sold, strangers going through her things or her kids having any of her things. This is such a violation of privacy to have strangers go through her things and private papers. Where are her rights? My mom made me promise her that I would promise to keep her kids out of her life. She did not want them to do the samething they did to my father when he was having mental issues after an accident. My father has always hated her kids since the time they got married in 1960. They all left home in their teens to get away from him. My father didn't want them around his home. But would allowed it sometimes for my mom. After his accident my father snapped and assaulted my mom and went to jail. Her kids got ahold of him and brainwashed him into doing things he would have never done. His own doctor told us he could have been brainwashed since he was having mental issues. My father never believed in divorce or creamation. My mom;s kids made my father loose his home to foreclosure, convinced him to divorce my mom who he loved, disowned his only daughter who he has always cherished and his only granddaughters who he loved very much. My father and I were very close. They had him put his cars in their names and change his will so they get everything of his. When he died they took everything from him and they had him creamated(which he was against) Now with him gone they are working on my mom to do the samething. This was the reason she wanted nothing to do with her kids. She has told many people about what her kids did to her. Now again she is going to loose everyhting just like my father. I have no money to even hire an attorney for her. The guardian is on her kid's side. Doesnt' my mom have any rights even though she has dementia?
