Caregiver to my 82 year old Dad. Problem: I am always angry with him even for small mistakes. Any advice?

Does the burst of anger include physical violence? If so, you shouldn’t be his caregiver any longer. In my state even with coronavirus nursing homes are ordered to intake residents. If you no longer can manage caregiving without so much anger that it scares either of you, it’s time to look into your father having another place to live. You’ll still be involved in caregiving, overseeing his care in a facility. He truly can’t change or help his behaviors. The only one capable of change is you. Good advice already given for looking into making those changes. Take small breaks, go outside and get fresh air. You both deserve to live safely and without so much anger, I wish you the best in making changes

Broken brains are hard to acknowledge.. But try to be less angry, and do not correct him so much.. One day, you may realize he has stopped talking,, that happened with my mom.. I corrected her one time too many, and that was it.. Speechless.. Never spoke after that...It was so very sad.. I can't really forgive myself for this and many other things that come along with this disease... It's not fun, and do not go down that road of guilt. I have, and I can't get out. She is gone now, and I still carry this guilt.. SO DON'T DO THAT... It's not good for anyone..
Be understanding to what is happening to him. He cannot help it. Do not try to make him see what he is doing wrong.. He will not understand.
This is your NEW NORMAL. THIS IS HIS NEW NORMAL. You start from here.. and you understand you are there to love this human, and care for this human, HE IS YOUR DAD... THIS IS HIM NOW.. He will not change back to what he was before.. he will keep going forward in the path of dementia. So be kind and understanding, he is not doing anything intentionally. He is your dad, love your dad, and be kind. Take a break, take him, well, not now covid.. try to get him into adult daycare so both of you can take a moment away from eachother. He probably needs to as much as you do.

Yusuf, perhaps you are burning out? I read in your profile that you are an only (like me) so lots of expectations and pressure. It is wise of you to take this concern out beyond yourself. You should look into respite care of some sort so you can have a break and get refreshed. It is a daily discipline to make yourself look at your father with different eyes than in the past. He can't help what he does anymore, his brain is broken. Many on this site recommend videos by Teepa Snow to help understand dementia better. Give it a try, as well as try to give yourself a break.
