My heart is just sick for you right now because I know what a dark place your in:(
To answer a few of your questions...
first, NO when we went to the elders about our 9 year old daughter being molested by a brother ( ex elder) we received no help. Instead we were in my opinion victimized yet again.
Later after watching us suffering one elder let us know they were " told to stay away from us." Nice, right? Talk about leaving a wounded family to tend to their wounds alone.
We did have our daughter go to therapy which she really didn't like. We have since been watching her closely for when she's ready to talk to someone again.
Our son is seeing a psychologist and I have been in and out of therapy for the past few years. Yes we are a bit messed up but we are strangely happy at the same time :) Leaving the religion was key! Now it's time to do whatever we need to do to have a new normal!
Just know, you will have your ups and downs but you're stronger then you think. The more you reach out and the more you feel you are doing something to help others the stronger you will get.
