can any song writers help another champ out?

im trying to write a song for me and my bfs anniversary and i havent been this motivated to write a song in so long, like i had 0 motivation for MONTHS and now suddenly its the only thing i cna think about.

I havent really gotten to the lyrics and although i wrote my own songs b4 its so mind boggiling to write A LOVE SONG without it sounding cheesy or niche

THE CHORDS ARE: G - Em - C - D and its those same chords throughout the whole song, and u finger pick the 5th string then the 4th, back to the 5th and then pluck the 3rd (if that makes sense anyway) if thats too complicated then imagine the tabs similar to anything by adrianne lenker. 

PLSPLS give suggestions & ofc any moots i can bond over this would be so poggers.
