She's been fighting Cancer for several years. She's been in remission for the last ~4 years or so. Her dementia has been progressing steadily. She gets pissed off everytime she can't find something (which is daily) like her sunglasses or checkbooks and falsely accuses whoever happens to be around at that time. She's fired and called to police on multiple maids, only to find her precious items days after. Now she's starting to accuse me. I think she needs a dose of TRUTH and texted her my mind a few days ago. She left a quiet, soft, and shameful apology the next morning. She lives with her husband that sleeps 90% of the time. I used to go over on the weekends and help her organize her house and occasionally pay some past due bills.
It's become increasingly hard to talk with and help her. I only have so much patience. I feel like: I want to help her (and I enjoy it) but she doesn't want to help herself. At times she thinks she's the only one in this universe. When I go out with her to the grocery store, she complains about waiting in line, as if she was the Queen of England or something, and I tell her, "everyone has to wait in line."
I think at times, individuals need a "knock-out punch of reality" to knock them back in place. Am I right here? I realize were dealing with a mentally sick person here, but also with one that needs to get a grip on herself and stop playing the victim, before she's completely alone.
I agree with FF, educate yourself, this is only the beginning and she needs your support, not your censure.
You need to arm yourself with as much knowledge as you can about dementia because from what you had written you don't understand how complex this illness can be.
