There may be no where to turn.

My mother is disabled. When I say disabled, I mean, she may some day be in a wheelchair due to her crippling rheumatoid arthritis. I am the only child, and most of her side of the family is dead or have moved on with their lives. My mother is in her early 60s and had a stroke last May. Her boyfriend, who she met online in 2007 after several years of searching when my stepdad died in 2002 of cancer, has health issues...and I don't live there with them because I have made a life with my boyfriend of 13-14 years. But my mom's boyfriend has epilepsy and is very bi-polar, and I cannot handle his mood swings. Today, my mom looked at me and said that he has been having vertigo side effects from his medication, and he did not remember a conversation they had earlier today. This set off a red flag, as I'm not sure if him having memory issues is a cause from the medication. This could be a deeper issue, and if he starts having Alzheimer's or Dementia issues, then we will have to figure out where he is going to go...because my mom can barely take care of herself, let alone someone who may need extra care themselves. Then, I have to figure out where my mom is going to go since she can't live alone. My boyfriend has said he doesn't want my mom living in his house (because he is the one who owns the house, not me), and they do not get along when it comes to me. They have butted heads in the past, and he will not be able to live with her long-term. Her side of the family have either died or deserted us. They do not have the money or the time to handle our problems, and I feel so alone in this. My mother raised me on her own, with no support. My father was an alcoholic drug addict who chose addiction over family, and passed away in 2018 from liver cancer. He was not a bad person, but he did not have his priorities straight, and was not ready for a family at the time I was born. His family barely talks to me, and they are not aware of the extent of my situation, and would not care either way what happens because they have pretty much washed their hands of anything having to do with my father. I have no clue what to do, or where to turn if things go south. What am I to do if my mother's boyfriend dies, or vice versa? My mom is planning on putting my name on the deed of her house which is falling apart (it has been since she moved in because the people who lived there before were upset that they had to leave. Their parents were selling the house), because she is afraid that her evil brother is going to find a way to forge her name like he's done in the past, so he can buy her house and give it to my cousin, who he wants so badly to move back from out of state. She has a family, and he wants her to have a place. He could care less about his sister, who needs help, and has told her he wants nothing to do with her or myself. We never did anything to him. We have been struggling, and all he has done is try to take the roof from over our heads.
