Hi Sandra ... Sorry to about your Dad. I've dealt with this personally with a friend and understand what your talking about. About the only thing that worked for me was agree with him all the time ,but always have a side step or trip/plan of you have to do this before you go or do what he is trying to do may help calm him down. Something like well you got to have a shave or have a shower or get some clean clothes on. Usually they forget that thought and calm down. You kinda have to keep agreeing but keep side tracking to doing or getting interested or talking about something else . It's not easy Sarah, not at all. I hate to say this but it's like treating them like a child but in a adult manner of promising them this, but we have to take care of this , before we can do that and it won't take long. I hope you see were I 'm coming from. It's almost like de-esculating technique for someone with a mental illness. usually his heart and kindness or understanding what is suggested will override his anger and rage. Firmness and lovingness will get you further along. Just my personal experience. Wish you the best.
