While the world may make you think you cannot be happy without finding that "one special person" in your life to have romance with, that is certainly not the case. While I do agree that love is certainly the key to happiness, romance is not the case. Yes, romance can be great, but certain moments of suffering trump it; those moments were when I cherished you in my arms.
The joy of holding you, hugging you, lifting you to see the world and that smile on your face brought me far more joy than when I dated your mother, and I enjoyed that very much. Yet even when you cried, hugging you to try and help you feel better would still give my heart joy. My heart would certainly be broken if you were no longer around.
I mentioned before that you are why I admire your mother so much more than before. Seeing the love she gives to you inspires me to be more loving, and as a result, feel more joy, despite when you could do nothing for me in return. Whether you were laughing or crying, holding you was precious. I would be at work and try to leave as soon as possible so that I may see your excitement and embrace you once more.
To have this joy, you do not need romance or even children. Helping others is something we can do all of the time, especially the handicapped such as your uncle. Despite being older than your father, your uncle's situation makes him like a baby both mentality and functionally, yet we love him so dearly. Love, even in small bursts, brings about great joy. I hope that you will remember that.
