It's wonderful to post here, but do any of us ever recover?
Absolutely. I have corresponded with a few. I look forward to the day when I will have "recovered". I think that the "blowing off some steam" is a perfectly normal part of the recovery process. Remember: we come from an environment where nobody is allowed to express any kind of independent thought. There is absolutely no disagreement or discussion allowed. It's very similar to the Communist Party under Chairman Mao. Anyone who didn't go along with the party line was punished or purged.
It is only natural for people like us who come from a totalitarian cult-like environment to blow off steam for a while. This is something that we were never allowed to do for many years. It has felt very good for me to finally be able to let out my true feelings and to be able to express them without fear. I certainly don't intend to stay angry forever. Just long enough to let it out. This anger had been bottled up for many years.
One cannot heal from deep-rooted anger until they address it, and then express it. When they have expressed it and dealt with it, then they are in a position to help others through the difficult process.
