Maybe some sodium crackers. Keep writing/journaling your thoughts. Also, try walking and listening to good music. Keep expressing your thoughts and you may be less likely to desire to purge.

I email my director. Which, as you obviously don't know my director (haha) you could type out a long, venting message to someone.

That and sometimes I lock myself in my room, then lock myself in my closet, blast some loud music and have a good sob fest.

Those are all good suggestions. If I could suggest, you could make a list of trusted people that you could call when you start to get the compulsion. I know how strong compulsion is, but if you distract yourself and catch it while it's still compulsion you might be able to pull out of it. If you don't act and it turns into obsession, you're pretty much toast, as you probably already know from experience. Good luck. xo

I find it helpful to get out of the house. What really relaxes me is going for a drive and blasting the radio. If that's not an option, I like to watch a funny comedy, come on DS, or call someone up on the phone to vent. Hope you can find some good ways to help you overcome this.
