If you are talking about the thread you started on the psychotherapy forum. You only left your post up 20 minutes before you deleted what you wrote. Your other threads were all replied to. I hope you'll consider staying and allowing more time for people to read and decide if and how to respond. I was one of the people who didn't get to your thread until you had deleted whatever it was you originally posted, so there wasn't anything to respond to at that point. This is a busy forum, but people come in and out at all hours of the day and night, and not everyone who reads a post will be in a position to reply. Some people don't know what to say, some people are simply reading rather than replying, some people don't have a similar experience so they don't reply, but given a bit of time (20 minutes really isn't nearly enough generally), someone will come along and reply, and then another; and when you respond to their replies it starts a conversation. Takes some patience.

If you do want to delete your account, you just need to PM one of the administrators and they will take care of it within a week or so (they do batches of them at a time I believe).
