I think I would ask his doctor what the difference is between serious and severe Dementia. I would like to know as well.
Julie, I will pray about Bill’s anger. Have you figured out what his triggers are? It can’t always be your fault, but he takes it out on you. Try to get away from him when he starts (or before if you can) and don’t say a word - just leave. Turn on loud music so you can’t hear him (or use ear plugs). Go to the bathroom and lock the door (or have one installed) and make sure you have a good book to read. And relax and tell yourself you will not be yelled at any more - for any reason. You will not be his doormat! You need some peace in your life and relief from his rantings. Please!!
