I send my deepest condolences to you for the loss of your mother and understand that every circumstance is different. With the utmost respect and tact, I have to disagree with your statement. I lost a family member to suicide who was in the advanced stages of a terminal diagnosis. After years of exhausting treatment options, he was ready to be done with the pain and discomfort. I can’t find it in myself to say that was irrational.
Absolutely, I understand that is not the situation we are discussing in this thread and was not the circumstance with your family member - and I am not trying to compound the grief anyone else is experiencing.
