Two decades have not healed painful breach in relationship

DEAR ABBY: Twenty years ago, I developed psychosis with a personality change. I did things I’m ashamed of. I had an affair, remarried and moved out of the country, leaving my 13-year-old daughter with my ex-husband. I snapped out of it 15 years ago with the help of a good psychiatrist and excellent medication. I deeply regret my behavior, and I have made every effort to change things. However, my relationship with my daughter has never recovered in spite of my apologies, sorrow and deep shame.
