Same here. Including watching my father decline, both physically and mentally, at the last couple years of his life. My dad and I were very close in my adult life, I think because we had many personality similarities that manifested in palpable ways. Seeing him decline, and experiencing the decline with him (I was his only confidant for a good while, and then the authority to decide to eventually to give the DNR) just reinforced my current idea and decision about ending my own life on my own terms, when I feel it is time.

I told my last T this. Never got a response about it.
