Obijuice, I'm not sure that I understand your question, but I'll try to interpret it as best as I can.

It appears that your question pertains to emotional trauma and it seems as if you're asking for a protocol to heal either a broken or damaged emotional heart, rather than a physically damaged organ.  If that is the question, the answer is that there exists no protocol, supplement, or other approach that will facilitate this.  No, fasting does not peel away layers of negative emotions.  

Fasting helps to cleanse the whole body organism on a cellular level.  This can contribute to "feeling better," but it is not a solution to whatever has caused the emotional issues.  Health and well-being isn't just a physical thing.  It involves the mind, body, and spirit and each of these vital components are linked.  When someone has experienced abuse for long periods of time, it is a statistical inevitability that they will develop chronic physical ailments, from Fribomyalgia to chronic fatigue and on to severe auto-immune issues.   

What helps to recover and heal a person's emotional health is to engage in doing the emotional work - identifying and processing emotional experiences and traumas, along with learning techniques to manage reactions caused by past traumas is a lengthy and arduous process.  This requires time, patience, diligence, and an openness to acceptance, as many of the "ah-hah!" moments come when we recognize that our past interferes with our present and creates certain patterns of behavior that only increase the impact of the traumas.

I hope this helps to answer your question.
