I just read your post which dates from 2011. We are now in July 2013. I have had several épisodes of depression and a fair deal of traumatizing events in my life. You have gone through so much. Maybe you should just read over what you wrote. Your depression did not just bloom out of a tree. What your body and brain were telling you is "System overload". I can't give you any advice as to how to manage all this or what changes to make because this is too personal. I just hope that you got this all figured out by now. Dépressions can teach good lessons as to how to live a more balanced life which will spare your physical and emotional state. Sometimes this means attaching more importance to quality than quantity.
Please accept my blessings and take care from now on.
