I moved in to my mother's over 17 years ago I was going through a nasty custody battle shortly after my mother fell broke her hip 5 months later my brother at 43 had a massive stroke this was not where I intended to be still you name it it's happened mother has 3 other daughters never stepped up they have threatened me with elder abuse to report me games lies the emotional mental abuse has been unbearable I've held my mother's hand through colon cancer and radiation none of them helped once nobody visits my mother or brother none of her grandchildren just recently one of my sister's called social security disability and told them I was stealing his benefits one sent a message to my mother's doctor and said I was giving her zanex and being abusive they told my mother I was going to kill her for the house she is 86 and gets confused easily and they call and tell her crazy things and she believes it my mother is a narcissistic and manipulation is her game yet her other daughters have become the Masters It's Criminal nobody will tell me who her POA is and one of the sickest things is my mother goes along with it and her answer is I don't know She's been legally blind for 15 years and she was getting paid to care for my brother after his stroke by the state guess who was really doing that she was just taking the check I could go on but I am angry I was never an angry person DO I HAVE ANY RIGHTS I FEEL LIKE IM DROWNING YET NO ONE KNOWS HOW TO SWIM TO ME
If your mother now has cognitive issues she probably can not change that.
I have to ask who is your brothers POA if you are also taking care of him.
If you are not a caregiver for your brother and or you are not his POA then you have no say in his care either.
I suggest that after 17 years you pack your bags and move to your own place let your mother, brother fend for themselves. They can contact your siblings if they need help.
YOU SWIM AWAY FROM THIS.
You need to work to support yourself . You also need to save money for your own elderly years .
Whoever has POA is the one responsible for your mother . If your brother has no POA he will be assigned a guardian by the court .
If you're staying because you think you are entitled to the house or expect to get an inheritance, these types of people rarely come though in that way, and then you will be homeless with no plan for your own retirement or the rest of your life.
So just leave them and all their toxicity behind and start rebuilding the kind of life you deserve. Please let us know how it goes.
