I have spent the entire day feeling every negative emotion imaginable because my mama comes back tomorrow. It is my turn to do the caregiving for a week to relieve my brother and SIL.
I also spent most of my time online today here on the site searching for inspiration and motivation. to help me make it through the week and not feel like I have been run over by an 18-wheeler full of bricks at the end of it.
I know she is sick, but still. How in the world am I going to make it through this week with my negative, energy-sucking mama who thinks everything in the universe is all about HER?
Can you take her out around other people, so it's not just the two of you? Or take her to day care, so you get a break? Give us more info about your situation and we'll offer better ideas, I'm sure.
Can you give us more information about your mom's health, physical and mental limitations; how bad is her Alzheimer's; when was the last time she saw her doctor; why she is being moved back and forth from your bother's house to your place; age; any resources that she might have that could pay for some in home caregivers to help you out; why is she not somewhere other than in your place or your brothers; and how long has this moving mom back and forth between you and your brother been going on?
It would also be helpful to know more about you like how is your own physical and mental health; how many others live in the house; when do you plan to see your doctor about how all of this is affecting you; and how long have you been involved with taking care of your mom?
Also, have you and your brother had a chance to sit down and calmly talk about her care needs both now and in the long term?
Who has Durable and Medical POA for your mother?
Have you done a search on this site about toxic parents, emotional blackmail, boundaries and narcissistic parents? There is much information here that could give you some tools to help you get through this week.
If you are this uptight just anticipating having her back, I wonder if seeing a therapist could help you. Not that there is anything "wrong" with you, just that you could use all the support you can get, and perhaps a med.
The question that always comes to mind with these kinds of posts is why are you taking care of her in your home? There can be lots of valid reasons and some pretty unhealthy ones, so that would be a good place to start your explanation.
