NewHeart.......I agree that you need to give yourself more credit for what you have done. I think that making amends, that you have, is a very significant thing.
You know---life is hard and we are all flawed, in some way...nobody is perfect all the time.
It sounds like they have forgiven you.....but, I think that forgiving yourself is more of the issue, now...?
You say that your mother suffered from anorexia and alcoholism, during your early years;
I believe that it would be of help to you to study the Big Book and literature of the organization "Adult Children of Alcoholics". The guilt that you feel, is one of the residual effects of having a parent that was an alcoholic when you were a child.
You can get the Big Book and other literature and workbooks on amazon.com, in the book section. And, your local library, as well.
Just go to amazon.com ...to the book section...and google "Adult Children of Alcoholics"
I think a lot of it will resonate with you.
