Recently I have noticed that some people I know have gotten various types of cancer about a year after being subject to workplace abuse--this is anecdotal, but it seems clear to me. Probably one of the great frontiers of medicine will be to connect particular emotional issues to particular physical pathologies--rather than just the general "sure stress is bad".
Pointing all this out is one thing................but what to do about it? I love the energy psychology techniques, and there are MANY of them. They are growing like wildfire though traditional psychologists have a long way to go.
Here is one technique that a lot of people love--emotional freedom technique. I am mentioning that in particular because there is a ton of free information on it, and one may be able to learn it from that. It has to do with tapping on various acupuncture points on the face, shoulders and hands while repeating affirmations of various types.
http://www.emofree.com/ One might state the problem and the solution in the statement--
"Even though my spouse is/was emotionally abusive towards me, I wholly and completely love myself and accept myself"--although it would work better with a particular situation. It would most likely be helpful for PTSD as well.
Again, this is just one technique. Another example would be EMDR--but this has to be done with a practitioner.
http://www.emdr.com/ I like neuroemotional technique, too. Again--I am a HUGE fan of all these things and have come to use a type of neuroemotional technique a bunch on my family and myself. It is amazing the physical change it can make in certain symptoms.
