I agree with multipixie9. It is important to remember that the 'splits' happened in order to help you cope with something you yourself could not. The idea of 'containment' frightens me because I'm afraid 'they' would simply rebel against it. Recognising these other parts of you as 'friends' may help. Even if one or two seem a little hostile. It could be that one or two are angry with you for putting up with a particular situation. Never the less, try to see them as more like quarrelling siblings than battle scared enemies. All said and done it's you, all you. I was once told that this was a kind of self-cure, a survival thing, something we do in order to survive. I was also told that people who do this, be it unconsciously, are smart people. Bottom line, fear makes the situation worse. Reading up on DID will help to put it all into some perspective and hopefully alleviate the fear.
