Could you help me to write a song about

About my friend. Her name Natasha.
She is very positive.
Theme: Love
*I spent a little time with her, she is very positiv, very kinn and clever. And i lost my chance to be a friend to her,even if i want to be more than just friend..
Could you help me with song please?

Well you could start by making your song a simple, a few lines or of lyrics or one or two stanzas is a good way to start.

Just start singing about her and see what comes to mind.
