Need a topline written for a track

I'm looking for a catchy melody and lyrics to a beat that I have ready, I'm only 13 years old & I'm not very used to this so any follow up questions, please ask me. I want the lyrics to be like Billie Eilish & the vocal melody in the style of The Weeknd. I'd like to release this song commercially.

Additional info:
I have the music and now need lyrics and vocal melody written. The song will be released commercially. I don't need to use your name - you can be uncredited. I need help writing both lyrics and a vocal melody. I'm looking for a male singer. I'm an indie artist.
