Hi sunshine,
I am sorry to hear that you are so sad, emotions create so many of the chakras to spin at irregular speeds, so your heart might be going too fast, the solar plexus too slow and the brow fast then slow, causing the thoughts to be all over the place, the appetite being lost and perhaps heart palpitations. Crying deeply from the solar plexus can balance this out, it can release much of the tension that becomes stuck in the electromagnetic energy field surrounding the body, stress does create many health problems.
I think you are doing very well considering what you have been through, talking about it will also help you release many of the feelings and emotions. You can only get through day by day when you have been triggered by such intense emotions, as you are not just fighting your fears of abandonment, you are actually fighting your programming.
