The situation is extra hard, as he is in your home. Hard to tune that out. I think he needs his hearing checked. Most likely the TV is turned up because he can't hear. If it gets annoying, pull the plug, or the breaker to turn it off. If he acts like a child, treat him as if he were. There should be consequences for poor behavior or rudeness. Being old is no excuse for being mean or rude. Not acceptable. I still think the doctor should be involved in this.

My mom died a number of years ago. Yes she was very, very hard to manage. I took care of both my folks as they declined and passed away. I tried very hard with my mother. I attended seminars for care-giving to help me cope with my mom. When she was terminal, Hospice had a program for families for those in that roll. Best thing I ever did. Your library or Senior center near your home should have this kind of help. Sometimes bringing another "Brain" into the situation may provide some help. Look into it if you can.
Being a caregiver to someone that is difficult may demand of you more than you can tolerate. Having CRPS is awful in itself. Also if this is effecting your BP, that isn't so good. That stress level needs to come down for the sake of your own health. High BP makes the CRPS worse. Try to get some council as you really do have a problem that causes stress and tears in your home. There is no shame in asking for help just for yourself, so that you can deal with it better. Sometimes we can't change another person. We can only change how we react to them. Do all you can do to lower the stress OK? Let me know if you find some agency that can help. Keep in touch and let me know how it goes. I wish your family would be more supportive of the whole situation. Husband should recognize this as being a problem. It can hurt a relationship too if things get out of control. You two need to stay close and communicate even more, while you deal with your F-in-law. Keep praying, and I will too. ginnie
