Pain
 

Pain begets pain

Talk about it, it revives
Think about it, it relives
Hear about it, it returns
Cry about it, it regresses
Sing about it, it reuses
Write about it, it regrets

Forget about it, it releases

Wow, loved it. Thanks for sharing.

ALl good apart from 'reuses' which was perhaps a bit tenuous? Can't say i didn't like the ending sentiment though. I'll go one better and say i did actually. Nice work.
