The commenters may be people who feel guilty about how they raised their children and who are defensive or it may be people who heard your story and their inner critic was projected out onto you, etc. Most of the time how people react to other people says a lot more about them than it does about you. I don't know if that helps, but it helps me at times.

You have a right to your own feelings. From what I have read, your therapist validates how you feel, and in time, this will help you feel more grounded within yourself, and less impacted by others. This is my hope for you and myself and all others who suffer

How you feel is not only okay, it is completely understandable, completely valid. You were neglected, you were hurt, and you owe no one any apologies. I am so sorry this happened and that your mother won't help you resolve this, you didn't deserve any of this.

Sending you tons of hugs.
