I'm dealing with my younger sister who is a Dr Jekyll and Mr Hyde type personality, with regard to our elderly mother, and having a very difficult time.

The situation: I live with our mother (temporarily) and she slept walk (again) and this time, fell around 2 a.m. and screamed. I texted my sister "mom fell, please call" but she didn't respond. So, I called her the next day, and her response was something like, "you always do this. you always call or text about mom's problems and it's a real inconvenience to me b/c I was up worrying about her."

Why didn't she just respond to my text by calling me when I texted her? A normal person would respond that way. Wouldn't they? No, I didn't call 911 b/c I checked my mom over and she didn't break any bones. She was shaken up, disoriented and babbling to herself.

So, then, after the phone call, I came back to our mother's apartment and my sister was there. Our attempt to have a civil discussion about working together to get mom into assisted living, spiraled out of control quickly and we are now estranged from each other.

However: she is the power of attorney. She won't grant me access to information I need, in order to move the process forward. I'm at my wit's end b/c I have no power in this situation.

I did call the county, and filled out a diverse population form, that my mom signed and that once approved by the county, gives me authority to submit an application to our county for medical assistance, which our mother needs to qualify for the elderly waiver in my state.

My sister "claims" she already tried to do this last year, but refuses to show me proof that she submitted an application to medical assistance on behalf of our mother. So, that is why I'm applying to be our mother's medical assistance application authorizer.

My sister accuses me of being an emotional terrorist which is ironic b/c she is the one who gaslights me, minimizes, counters, shames, and deflects with me whenever I try to hold her accountable or set boundaries with her. I already blocked her and her husband from my Facebook, but I'm still Facebook friends with her daughter, my niece. She is the type of person who presents herself as the family 'hero,' because she is married with kids, and I am still single, without a full-time job.

If I can get that application filled out and completed on our mother's behalf, she automatically qualifies and then I can find her an assisted living facility to move into once a room becomes available.

The fallout from separating from my sister is her 3 children, whom I have a great relationship with. I'm moving out of my mother's place in 2 months, to where yet, I don't know.

I can't stay here anymore. It's toxic to my mental health. I need to get away from my entire family of origin. I'm 48, so I really need to get away from them. I'm already estranged from our brother and his family. Once I move out, I will have no family of origin contact anymore and that's a lot to take in.

Has anyone been in this situation?
