Yes I've done this before - its simply a reaction to an extreme amount of emotional distress. We feel we need some finality, a line drawn under something difficult we feel we must move on from.

What was it that triggered this? Sadly even PC is not without conflict. I don't entirely agree with the procedures for dealing with it but as the ignore button and option for board deletion is all we have - you can only but make full use of it and see whether that helps you to feel more able to cope with resuming normal membership here.

It may have been something else entirely in which case I hope you get a resolution to it soon, sometimes all we can do is make a clean break and continue life without that person, place or whatever. I hope it doesn't come to that for you though
