(((Nik))) I think you should take a break for awhile. Mine wasn't the same situation, but I trained and then worked for the shelter here for battered women and their families. It was very difficult, having been terribly abused physically, emotionally and verbally by my ex (and only) husband. I had to give it up for my own health and well being.
What you have been through is tremendous. I don't think at all that you would be giving up helping others. We all know what a supportive and loving person you are.
You do go ahead and give it a few days. I just worry about your own emotional and physical health trying to help these people after what you've been through.
Much love.
