JJ, you have to steel yourself against that sort of thing.   I know it
hurts, but it really isn't rational, and they really can't be made happy.
It is not really anger against you, per se.... it is anger against the
feeling of being out of control of their lives.   You are handy, and you get
blamed.   Neither you, or anyone else in this world can change that.   The
illness is what it is.   You can't make her capable of managing her own life
again, none of us could.   If it was in any way possible, all of us who post
here would have moved heaven and earth to make it so, and many of us surely
tried, with the same result.

It isn't the place, it is the illness.
It isn't you, it's the illness.

I think you are doing the right thing, and leaving her alone for a few days
will be the best of all possible solutions.   I know you are going to feel
guilty about it, because you are a good and loving daughter.   Your mom
can't reason anymore to tell you that, but we can tell you that.   She needs
to adapt, and you know how they find it hard to get used to new things.

It is the very nature of the illness that they are always in new
surroundings and meeting new people every day.   It hurts when they blame
us, but they don't understand, so you shouldn't take it personally.

My mother in law used to get lost going right across the hallway from her
bedroom to the toilet.  Then she would get lost and try to get in my bed
instead of her own on the way back.   She wanted to go out and feed the cows
(we have never had a cow in our lives) like she used to do as a young
teenager in Estonia.   She imagined she had a baby (at 83).    She was
irrational and at times it caused us grief, but it was the illness.

Remember always, your mom's brain is broken.   She can't reason anymore.
Behaving irrationally, or getting angry irrationally, is part of the
sickness.   You are a good and loving daughter who has done all she could to
make sure she is safe and cared for.   You need to tell yourself that every
day.

JJ, just to add to what the others have said and agree, , but I think others
have said this, and I did and I'll say it again, leave here for a short
while but at least *several days*, she needs to get at least partially
settled in, every time you go back you are unsettling that process,
reminding here she can be somewhere else and giving he an opportunity to go
back, which isnt going to happen, no one person can cope alone its simply
not possible.

Make sure you do what you say you are going to and take some time off for
*yourself*, rest,and when you do go back, DO NOT ASK QUESTIONS about what
she has been doing or anything like that because chances are she wont
remember and she'll just make it up, bear in mind that a large part of what
she tells you likely isnt true in any case ....my dad would swear blind he
hadnt eaten all day, what he meant was that because he couldnt remember
eating, therefore he hadnt.
