Oh Barbara
Stay strong if you can. I have only just read your recent posts, and have a mental blockage on previous posts, but just to say you will want to do what you can for mum.
If you have the power of attorney form, signed originally by mum, you don't need anything more other than to register it. Do it now, love. Never mind what your mum says or doesn't say, do it. It means you are then in charge of her finances if need be.
If she hasn't signed it, and you now think she is incapable of signing it, you will have to apply to the Court of Protection to get POA.
Once you have the POA signed everything is in your hands.
Oh, I feel for you. I didn't experience any resistance from my mum, she was glad to leave all decisions to me. Your mum is more feisty, Yes we found the medication clearly not taken, it is a nightmare not knowing what she has been doing.
Aw, "let her sink or swim". I hope that was a rash reaction to your stress. Hope you didn't mean it. I can see where you are coming from. You can take a horse to water, but can't force it to drink. It is hard work, and not easy if you have other demands on your time.
You sound so distressed, hope we can help here on Talking Point. Stay with us Barbara and let us help you through this.
Much love
Margaret
