Doing Shadow Work to Eliminate Old Patterns

I feel I am at a crossroads in my life. I am 57 and have two children one who is married and the other who is about to leave to live in her own apartment. I divorced my husband around 20 years ago after suffering a lot of mental cruelty. I separated from my last partner two years ago after nearly 14 years together as I felt I was losing my identity in our relationship. I recently left my job as I suffered bullying at work and could not stand it anymore. I am hopeful of a better future but I feel I have hit rock bottom and do not want to repeat my old mistakes. However I feel that I have not learned anything and will somehow make another bad decision. Have you any suggestions for me that might help. I have read your book the Seven Spiritual Laws of Success many times and find great peace within.
