I think you have to let this one go. That is the way of this site.
But I understand. I sometimes feel like I can't reply to a person who has made just one post. They post in fear, and then disapear once they get sober. Most likely to embarrassed to come back. But the door is open.
But I look at this way now. This is ONE of my way of giving service. I try to spend an hour (+/-) on this site everyday. And if I can say something that may help someone, even if it is not the original poster...then I am getting out of myself, and giving.
I remember when I was in rehab. The 30 day programs. One of the ways it works is that people come in and leave at different times. And yet, some of the clients would get upset because they felt resentful towards "New" people. And/or resentful at some of the people leaving before them.
I never really understood this. But I think that when we are all in such a vulnerable state of mind...change is so very difficult, and disruptive.
