[Shakespeare's Strumpet]

It's natural to get a high after you cut. When you hurt yourself (intentionally or accidentally) endorphins rush to your brain to alleviate the pain (natural pain killer). Endorphins cause good feelings, or happiness. It's been suggested (but never conclusively proven) that people who have a tendency towards self harm release more endorphins.

The important thing to realize is, though it may feel fantastic/calming/insert happy feeling here, it will only do so at the moment, and then after that comes the crash of guilt and self hate and the need to repeat the process. Plus, we all know that pain killers are addictive. Pretty much, people who self harm are addicted to natural pain killers.

And yeah, I miss it too.
