writing my first song

Normally words come to me so freely. It's a few things that I feel passionately about;

Music, Writing, and Family.

 I could rant for hours about music, writing, or some random story about a crazy cousin of mine. Recently, I have been trying to write a R&B song. I spoke with some people who have experience with music for advice. 

He told me about bars, verses, choruses, and bridges. One thing he told me that I have been trying to keep in mind was, "Keep everything as simple as possible." Of all the information he gave me, I grasped it all except the bridge. 

Now I find myself in a terrible funk.

I don't know what I want my song to be about, I have been struggling with my bars, and I still don't fully understand how to work bridges.

My biggest dream is to be able to do this, but it feels so hard!!!

UGH

I'm so frustrated. Hopefully this will come to me soon.
