Hey, Sparque - Zoe made very valid points. It is never a good idea (no matter HOW much we think it might help) to disclose any personal information about what we have (or, have not) Survived.
When we disclose personal information, it opens up the counselor/client boundaries, among other things. Another problem of allowing clients into our personal lives is that it takes the focus off of the client's issues - whether we mean for this to happen, or not, is not the point. The client will, more often than not, view a disclosure as a sort of one-upmanship EVEN THOUGH the disclosure was not meant in that way.
So, I agree with Zoe 100% - keep your Self to yourself where your clients are concerned. In the meantime, I would strongly urge you to seek your own personal counselor in order to help you to process some of the information that you've already witnessed and to help you to prepare for those events that are yet to come. Without an objective eye, most counselors to at-risk kids invariably become jaded, overwhelmed, desensitized, and lose their desire to help these poor kids.
