Sounds like my mom and my partner’s mom. The older they get, the worse it gets. They basically become unable to care for themselves. My mom did the same thing to her friend after we had her involuntarily treated and she refused care. She fled to Maryland to sleep with her friend somewhere in her home. It’s been several years since I have spoken to her. If she refuses treatment, I absolutely cannot have a relationship with her for my own mental health and sanity.
Your mom needs help you cannot give her. She is not going to care for herself and she isn’t going to seek treatment because by now if she’s gone to the doctor presenting with the stuff she says to you, I’m sure they’ve tried or at least suggested outpatient treatment. She’s likely already refused a few times too.
My mom was diagnosed with a personality disorder, being delusional, and likely schizophrenia (she won’t confirm it but the symptoms are such) and this was after involuntary treatment. She refuses meds,refuses help so she could live independently, and lives on the run.
Your future does not look or sound bright if she continues to refuse care and make you her problem solver. Eventually, she’s going to turn on you. They always need to be the victim. Take care of yourself. You may want to consider involuntarily committing her to get her the care she needs and to get a treatment team in place to get her back to living independently. Your sanity and safety is important! And first.
