I have a lot of compassion for your situation, because I know how it does feel like to have parents who are not balanced. I had to escape from them when I was about 22 years old. It took me many years of meditation practise to recover a bit from the damage they did to me.
I think that you have good luck that you have met the programs of Learning Strategies.
I think that it's important to have a regular practise (like meditation with Holosync of Centerpointe, the Sedona method or programs from Learningstrategies). Their CD's can help you to find a new basis for your life. They can help you to get more balanced, more stable and to get more competent to deal with the different issues of life. At the same time they do not great any dependency towards a physical "master" who might abuse of his power and you can listen to CD's whenever you have time.
I myself had a very difficult past. I use regularily holosync meditation from Centerpointe, the Sedona method and courses from Learningstrategies. I look at it as an investment for my future and I practise and look at these courses as my personal path and as a substitute for ordinary meditation practise.
