Dear Amber,
I am so happy that you are doing well. You deserve all the happiness that life has to offer.I think that your letter will be a wonderful gift to your children.
Mine journeyed with me as I went through all the ups and downs with my M. They did not own my "issues" as it was "obvious" that the issues were mine.
They developed a strong bond with me , partly, b/c I was "real" about myself.( I figured that I might as well be "real" b/c kids can feel it anyway.) I lived with so many lies in my FOO that I tried to be honest with my children.
I think that writing the letter will be a wonderful bonding process for you and them. You can free them from any of your issues that they "took". You can bond as human beings in a deep way.You can touch each other on the deep human level and cement your relationship with them, even more.
Love Ami
