Do you remember the serenity prayer? It's time to let go of some things if you want to bury the anger and hate and have a better life.
The point is this...every minute that you take out of your life to try to "make them pay" when you can't see any results is just that-time out of your life.
I am sixty. They took over thirty years of my life, and if I "go there" and start thinking about all the time I spent in the borg, I get depressed, angry, and just really sick. I don't want them to take any more of my life, so I do not allow myself to think about them much anymore. It thoughts creep in, I take a deep breath, and conciously go down a different path.
Here is my advice-when mom calls, and starts talking about all her happy service-interrupt-say, "Really?" then tell her your news. If she starts talking about abuse-tell her in no uncertain terms that you are through pursuing it with the elders. Keep repeating this as often as necessary in as few words as possible. Don't go further into the discussion. Don't bother downing the WTS if you know how she'll react-YOU are the one who will have the ill effects of the conversation.
You need peace. Hate can eat you up inside.
I can't say that I have found full peace (will that ever happen for any of us?), so know that I am not "cured" by any means. I was not abused but my child was treated horrifically by elders who then proceeded to treat my husband unbelievably cruel.
I cope by keeping my mind totally occupied. I am almost through getting a college degree while I work full time. It keeps me super busy. On the other hand, I try to get outside and enjoy nature, to destress. Nothing like a vacation to the mountains to uplift.
Take your girlfriend by the hand. Go to a beautiful outdoor place with a picnic lunch, if possible. Take that deep breath. Don't let them take any more of YOUR LIFE. You deserve to live...you deserve to be happy....YOU CAN DO IT!
