Writing poetry is like giving birth. Sometimes the birth is painful, but it only hurts for a little while. The end result is a beautiful new creation for all your efforts. Force the reader to experience what you've been through. Help them to hear what you heard, see what you saw and experience your senses.
Truth is better than facts.
It's your story, write it the way you feel. Dig to the depths of your soul until it hurts. Get your feeling down on paper. Write as if you're never going to show it to anyone else. You can always take it out later.
