I am new to this, but the time has come that I just need to share and hear from other people like me. I am at my wits end, and I know that this person that is inhibiting my mothers body is not her. She has gone in to decline much faster than I expected. She refuses any type of medications. And yesterday I lost it with her. I just had to get up from the dinner table and go to my room and cry. Please tell a type A person how to stay calm .


This is too much for you to handle alone. Your mom's world has totally changed for her, and that has changed your own world. It sounds as if she has dementia. I would call your local Alzheimer's association and ask for help. They have information for you, and probably substantial support.
Please keep coming back here, too. Know that you aren't alone and that many people share your distress.
As for staying calm with her, it often helps to just go with her notions if they aren't harmful. How she views the world is as real to her as your reality is to you. Often, just agreeing and moving on, or distracting her from what she is saying or doing, will help.
If she hasn't seen a doctor lately, she may need medication adjustments. And a support group would be good for you. You maybe should see your own doctor about your stress. Caregivers suffer from great stress and often depression. Don't let this affect your health, and please don't let guilt over inappropriate responses eat you up.
Seek to learn, get respite help so you can get away when you need to. You were right about going to another room, by the way. Even that can help.
Please keep coming back for support, here.
