I think you should write a letter, but make it a love letter. Just pour your heart out to her about how much you love and cherish her, and find every good thing you can say about her, and express your gratitude for her influence on your life.

Do not mention anything at all about any issue, current or past. Just pour out some love on her. Give her a blessing. Affirm her in what is most important to her. Step into her shoes and show her you understand her. I think it will change your life.
