I once read a great book by Stephen Covey, called "The Seven Habits of Highly Effective People". Many points and teachings from this book had such an influence upon my life, that I was able to fully integrate them into my personal beliefs and choices thereafter in life.
One such example is: There is this whole section that talks about that period of time between action and reaction, and it discusses how in that time period we see HUMAN CHOICE; It thereafter goes into encouraging response as opposed to reaction, a place/time that every human being can acknowledge and capitalize on as a human gift having been given them. - The gift of human choice.
Just one thing that I personally put into practice until it was a guiding force in me, is that I decided that I would strive to never allow my mood, present-time reality, attitude, sufferings, or you name it, get in the way of me responding to others, (NO MATTER WHO THEY WERE), as a thoughtful, loving, decent human being. And, why because I could and this was gonna be my choice/my response and not predetermined for me.
And, thereafter I have personally chosen many responses to things based upon my values and guiding principles that I value, rather then imposed, predetermined controlling reactionary responses that are often more socially acceptable and rationalized.
For example: I had bought my eldest sister some lovely lingerie and my mother a $50 dollar gift certificate for Christmas one yr. Well, eight days before X'mas arrived she beat me almost to death, and drove a steel ashtray into my face, scalded and bit me, while my mother cheered her on and yelled in my face that I f'n deserved it, disregarding my cries that I give up. You win. You can have me.
Real point here: eight days later on X'mas morning, both family members received there gift from me, because it was my choice, not there's to predetermine.
So, because I don't even like my Ptsd to predetermine my heart, choices and response to people, I remove myself from its thinking (when I can) and respond to people from that part of me that is actually me, (and not my symptoms or suffering) while reflecting my heart and values and choices.
Remembering that I still have Human Choice, (another words they didn't turn me into an animal and can keep me this way).
This is now a well ingrained response, and heart response based upon my values, but unfortunately it can be misleading. :(
