Ok...have a few minutes to respond to this. I'm so relieved and happy for you that the Dr. recognized what she did in you. This, I believe was a crucial turning point for you. I believe you needed someone to explain to you how the brain handles stress like you have been experiencing. It's your body's way of protecting you. It is also I believe why so many abused people can convince themselves things aren't so bad....because their mind helps them to not remember many things...or it clouds the memory so that you aren't sure really what did happen...I remember experiencing that same thing.
Having this brought to your attention, coupled with your type of personality was likely to switch on a light for you....and it did just that. Fear is a powerful master to someone who has been through things like you have....and abusers use that fear to their advantage, you are taking that advantage away now.
You are absolutely going to amaze yourself at the strength you are gong to find you have.
