Wow. Thanks for that, it is inspiring (and sad and happy and tragic and an education). I admire your strength and courage. One thing that really struck me was the "I did all I could."
That is something that was really important for me too. at the time. It's difficult to watch your loved one circle the drain, and for me it was nigh impossible to not try to stop that from happening. Like you, that led me to insanity, a change in personality, and constant resentments, which sucked my soul away.
It is interesting to see that the progression of our addictions to our loved ones seem to mirror the progression of our As' addictions.
Congratulations on breaking the cycle, and thank you so much for sharing your experience. (cyber-hug from cyber-stranger) to you.
