(((Renee))),
I'm so sorry for you. I used to work with Alzheimer's patients and while it was a very rewarding job, it could be extremely frustrating at times too. When one of the residents would say something mean or do something weird, I just had to remind myself that it was the Alzheimer's doing it and not these lovely people I'd come to love. So, you do the same. When your parents pull this crap, remind yourself that they wouldn't do it if they weren't brainwashed by that horrid organization. Remind yourself that deep down, your parents love you and would show that love if it weren't for the indoctrination.
