Caring for a bipolar mother with cognitive impairment due to a stroke.

Yes, enough is enough. It's not fair to your daughter and your husband to have her there ruining the atmosphere in your house. And certainly you have done more than your share for her for four years. The stress will ruin your physical and mental health. So she needs to move to a facility. Talk with an elder law attorney and/or a financial planner in necessary for how to finance this (NOT from your own money, but from hers). Let us know how it goes.

While this is now water under the dam, I can't help but wonder why in the world you would allow your mom to move in with you knowing that she dislikes your husband? I mean what were you thinking?
And here you are 4 years later and you're living to regret that decision. I could have spared you the trouble had you asked us if she should move in 4 years ago, as we all would have said a big fat NO!
But I digress, and like I said it's now water under the dam, so now it's time to get the ball rolling into getting your mom placed in either an assisted living facility or memory care. That way she can be around other folks her own age and you can get your home back and more importantly, your peace.
I wish you well in finding the right facility for your mom.

I hope Mom has funds and can go to assisted living . If so , tell her this is no longer working and she needs to move .

Or have Mom go to adult day care while you are working .
