Thanks all of you for your suggestions. I will definitely consider all of them.
Abundance for Life is definitely a course I'd like to experence and benefit from but is just out of my budget for another several months.
There's a sense of me that also feels cheated, not understanding my behaviour or the choices I made, and I'm hoping that these suggested Paralimals would help the healing process.
Unis (or anyone else), would the New Behaviour Generator also help ease my obsessive thoughts concerning the actions of another person or would maybe Break the Habit be also useful?
