loopylou - you say that you are having counselling due to some things you discussed on here. I might be wrong but isn't that a good thing? I thought the point of counselling was to help with problems you have in your life, therefore the things you discussed on here may not have come to the surface had you not opened up...The problems were there in the first place, Mumsnet maybe just allowed you to see them and begin the path to recovery (this said, although I've been on mumsent for a year now I have no idea what your problems were/are, so they don't stick in the minds of all the readers) Counselling is a wonderful opportunity to get some advice and help, try not to feel stupid about sharing.
I've had some really personal things on here too -some things I've not discussed with anyone else apart from a v close friend, I've had a little paranoid spell of 'oh my god, but everyone in the world can read it' in the past but hell, I don't think I'm THAT interesting really and if the world wants to read about my little life so be it! I too am a terrible blabber mouth but everything I've blabbered on here has always been met with reasonable, helpful and above all very friendly comments from others. Through this I have gathered a wealth of knowledge (or at least borrowed it!) and met a bunch of lovely people.
I think mumsnet talk exists on lots of levels, one for advice regarding parenting, one for sharing anecdotes, one for deeper discussions of a private nature. It is up to the individual how much info you discuss, I think as an adult human being we ought to be taking responsibilty for our own actions and keep remembering it is easier to blame others rather than see parts of our personalities we might not be too enamoured with. In this case the effects of being a 'blabber mouth' -sorry if that sounds harsh, but it wasn't against your will that you wrote these things, perhaps counselling will help you there as well. Perhaps there is a leson for others to learn here too.
Sorry to go on and really sorry that you're traumatised by it all - honestly I wouldn't wish feeling terrible on anyone. I guess only you know why you feel this way, and I do hope that you get what you need from the counselling...
PS I think if you've made a specific request to the team not to publish anything they really wouldn't - I mean they are real people, they have morals.
