I took her to the Dr and there is no infection. I closed the bathroom door as an solution, but she gets very upset, that she will leave for ever. No matter is you try to keep her busy, the bathroom is just an obsession. Please give me some advise what to do. It's so frustrating.
Sounds like you need to place your mom in a facility for your good and hers. You are showing a lot of stress and it would be better for all of you if she wasn't with you in your home.
I'm real frustrated with my mom too. She talks incessantly and asks the same questions hundreds of times a day. Sometimes I want to scream and sometimes I do!
My mom is a narcissist and a super serious person. She couldn't smile if she wanted to. Unfortunately, she's miserable and makes everyone else that way. This type of behavior negatively affects the caregiver. A person can only take so much before they blow.
Please check your local library for a Senior Guide for housing, Assisted Living, Memory Care and other options. The booklet is behind the counter, just ask the librarian for it.
It sounds as though you're at the end of your rope. Place her in a facility soon, before you act out physically on your anger.
