I am really into music but I don't know how to write one ,can anyone help me please,…a song about love or anything,…

No one here will help you write a song. We're not set up for it to add musical accompaniment, and our main music guy no longer posts on this site.

Write down the love that's in your heart for another person or persons (parents? siblings? friends?) -- it doesn't have to rhyme. Then find someone who plays piano or guitar to help you with the music part.
