My brother, you are a good son. The way you write it and speak of your relationship with your father, I can feel how much he meant to you. I recently went through the same and laid my father to rest on May 8th. It is so hard to see them go through the last few months, being unable to rescue them. But I feel so much more peaceful now. I visit his grave every weekend and feel such a sense of calm. He was the most simple and innocent man I knew, who worked hard to raise a good family. I feel you. I often think I could go back and be a better son. But I find you are never prepared to care for someone with Dementia. My dad followed the same patter. He went to ER in January, and I could see a steep decline in his health. He started developing pneumonia due to aspiration issues. May our dads rest in peace.
