If you're angry, you don't have to write a poem dealing with the cause of your anger. But it needs to be an angry poem. So go ahead... write one. I know you're at least a little bit angry with me. And when you're done with your poem, decipher it as if you'd just found it printed in a textbook and know absolutely nothing about its author. The results can be amazing...and scary. But it's always cheaper than a therapist.
