It sounds as though it is helpful for you to talk about it, and it might help your mom. I had the experience of having my younger brother call me a few years after I left home, to confirm some things that I had been very confused about (did it really happen like that?)----I wish he and I had had the opportunity to talk more about our family as time when on (geography, finances, and emotional barriers...)----It does help to have someone who can understand what you are talking about...and who has experienced the same, another perspective from the same scene. There is a validation.
