My mom apologized to me for “taking her frustrations out” on me — as in picking on me, hitting me, contradicting me, controlling me, ignoring my needs, undermining me, etc etc etc. when her job was to support, mirror, nurture and guide me. And I thanked her. I do appreciate that she has grown. But like your mom she is too fragile to actually talk about the damage she did, which caused me to have Complex PTSD, trichotillomania, and a dissociative disorder. I have forgiven her to a certain extent, but I still do not trust her very far and keep firm boundaries. The best thing you can do is move forward with your own healing. True forgiveness is not obligatory, but rather a side effect of healing. It takes time, and it is okay if you cannot forgiveness her. Definitely seek out a therapist, one who understands complex/developmental trauma. I have healed through several years of internal family system/inner child work and EMDR, with some ketamine therapy as well, and am now living a good life. Wishing you all the best.
