While I am sorry to hear that your plans with your S11 have changed and that it, understandably, caused you a lot of pain, the tone of your voice in this post is amazing. You really have healed so much from just a few months ago. The strength in your words resonates and, while it was painful for you, you made a choice thinking of your son's best interest. This, of course, is in keeping with everything you have ever described doing for your boys here on this board, so it's not surprising. It's just impressive that you did not let it send you into a tailspin.
I am glad to hear you will have more time for your own writing. I am sure that will be a good thing for you.
I agree with Coach; you are, absolutely, a success story. This journey is about saving oneself, healing, growing and emerging better and happier. You sound like a man very well on his way.
