This creative nonfiction story really gripped my heart, @abdul-qudus. Those big life questions about what we are here for, and that haunt many of us for a good portion of our lives, are hard to explain. But you have done so, beautifully!
I was amazed that you mentioned Zach Sobiech's song, Clouds. He lived here in my home state of Minnesota, and one of my neighbors is close friends with his mother. When he decided to dedicate the end of his life to creating a positive story with music, he became an international sensation. What a wonderful way to devote what remains of your time here on earth!
I thought I would share the song you mentioned, on YouTube. This was posted shortly before he died.
And here's a link to the movie, for those who may be interested: https://www.disneyplus.com/movies/clouds/7BGWoWi2mVpk
