I've written a song awhile ago but I've never taken any music lessons in my entire life and I do not play any instruments. I have someone who is wiling to sing it for me but they say they need a melody. I do not know how to write one. I was hoping you'd be able to help me out with this or if you have any tips on writing a melody. I was thinking something slow paced as well.

Here's the lyrics to the song.
