I am thinking of writing a letter to my mother as well. I'm going to do it eventually, I'm just not 100% sure what to say or, more accurately, how much to say and what tone to take. My goal is not really to find closure or healing for myself so much as to put an end to her continued efforts to contact me despite my unresponsiveness after over 22 years of not communicating with her (after years of emotional, verbal, sometimes physical abuse and neglect she abandoned me when I was 15). She's delusional, so I have to be concrete and fairly brief.

Anyway. I identify with much of your letter, and applaud you for writing it. Takes courage.
