Touching on what LisaRose stated, it sounds like you may be dealing with PTSD (post traumatic stress disorder) as well, which many ex-members of mind control cults deal with. It can come in cycles throughout the years until you heal fully, whether on your own or through the guidance of a professional therapist.
The peace we seek is already within us. It's a matter of connecting with ourselves and building the foundation starting from within and extending out. Not, outside extending in. It's a lesson for most of us to learn, some don't and then go on through life reaching outward, pulling things in to feel better until that job, partner, home, religion, drug or alcohol choice collapses and we hit rock bottom coming to this realization.
