I worked with hundreds of women in codependence anonymous, closed surviver groups and Al-Anon and I am used to sharing.
The vipassana I took was taught by SN Goenka (www.dhamma.org and it's free) who died a few years ago. You get an assistant teacher and video tapes of lectures. I was able to do a retreat with SN Goenka years ago and found his assistant teachers just as competent and helpful when you are needing clarification. The retreats are very strict, no mixing of sexes, men and women stay in different buildings when resting and sleeping. Depending on the center you may have individual rooms or bunkhouses and usually everyone meditates in a big Dhamma hall. What I found was I was grounded back in the body, trauma kind of cuts the body and mind off from each other. The technique digs up all sorts of stuff though, stuff we've been hiding from so this is kinda like bootcamp vipassana. It's dive in and you will either sink or swim. You can't take anything but yourself into the retreat. You will meet yourself or what you think is self...hehehe
You have to take retreats for enlightenment, as a Boddhisatta, one who seeks enlightenment to help others...It's not an arhat practice, which is really weird because Theravada Buddhism feels there is only one Buddha until all the lessons Buddha taught die off and then another Buddha comes into the world. I think that's done so when you go sit in retreat you are not looking for something personal or get rid of something. What happened to me was a side-effect of practice.
