It's like AA for me. People no doubt saw me drinking and out of control and pitied me. But a non-drinker would have no idea that that was a comfort zone for me at the same time that it was a terrifying place. It was horrible, yet it was what I knew. So... I know people who drank as I did. And they understand me. I don't deserve a prize for quitting and becoming a responsible person. I do need people in my life who understand in order to continue to know what my problem is.
You can make all the analogies... We are here. And although I didn't do the N thing relationship-wise, I can see that it would be "comfortable" to repeat and live in what you know.
Love to you sea, and don't be hard on yourself. If they don't understand, give it some time. Take it easy, vent here, and let some time pass before you expect to see your friends change their opinions.
