I lost my mom and dad when I was in my twenties, one to a long-term debilitating illness/stroke and the other to catastrophic cancer with just one-year survival. after diagnosis. It was a while ago, but one doesn't get over it soon. This will doubtless affect Jiri, so I hope he has a support system. It weirds me out a bit to know that people my age still have living parents - especially when they are not close to them while they are all alive and have the opportunity to be a family. In a way, I was lucky to know my time with them both was limited. I treasured the time I had with them on Earth.
T, you know I am thinking of you. I know you're strong and will deal with this situation accordingly. One of my acquaintances once said, "I don't know how you dealt with losing both your parents when you were so young." I don't recall being given a choice, actually. You play the hand you are dealt, if you're smart.
You're smart! I know you will be a winner in this game, and will handle it magnificently.
