I hesitate to say anything as the demo's made and you won't be able to change anything....
If this was a work file I would have said, (to me) there's a few problems. There's a huge jump between the first verse, (well set up) to the pre. If you'd explained: ....and now it's Sept. 19th her birthday's come around again-the day etc. it may have flowed better. The chorus doesn't feel like a chorus to me-more like a bridge.
This verse appears to say what a chorus should:
I’ve missed all the candles and wishes
First steps and pretty prom dresses
Wish I could have shared them all with you
But that’s the price I’ve had to pay
For the choice I had to make
Hope you understand what I had to do

Some good stuff here but a few problems as well. Best of luck!
