1) Draw an effigy of them then rip it to shreds
2) punch your pillow...
3) write a letter then tear it up (or send it, though that might cause trouble!!)
Other than that, I don't know. Are you angry with yourself or someone else??
If another, confront them?
I don't really know, I'm just making random suggestions which I've heard can work :blink:
Hope you feel better soon
