I had no idea about the surgeries and chemo. That is really rough. All I can say is keep fighting, you can beat this! My mom went through a period of coming out of remission 4 different times in a 6 years. Chemo and radiation, completely bald 5 times. She refused to quit and 20 years later she is still alive. Prayers and good thoughts to you and your family.
And yes, do what you want! Live life to the fullest! Cherish each and every moment you have and especially those with your family. But honestly that shouldn't be at the expense of someone else. For whatever reason if you don't like Kass then just ignore her. To continually insult and belittle her publicly isn't who you are. I don't know much about you but what I do know is you are a man with a kind heart. You are someone who readily opened your home to some children who were in need.
This forum has never wanted you gone. It's Papag they want gone. You they want sedated or at least heavily medicated.
Folk hero?!? Not even close.
Stay strong, I look forward to the day we can share a drink or two.
