Just use feeling and emotion.

Just use feeling and emotion,
write what your heart is bleeding.
Keep in mind poetry doesnt always have to rhyme.
Take care.

Couldnt have said it better.

I agree

While I agree with the sentiment here, the trap people often fall into with "emotion" is that they think it's all about personal experience. A good writer can tell a story about something external quite easily, but a great writer still puts their emotions into it.

I would never consider myself a great writer, but I don't see the point in writing poems solely about myself and how I feel about things. Writing about other things is much more enjoyable.

I agree :)
my poems are full of emotion and just flow from the heart, well most of the time :P
