This sounds exactly like my childhood. Only no therapy had a part in this treatment for me. This was just how the various generations of abuse were continued in my family. I was denied outside relationships of any kind. I was frequently called a liar "making things up", or just plain told I didn't "remember things correctly". It reached the point I still question my own thoughts and memories to this day.

I am sorry for all you've been through. I feel bad for any child that doesn't receive the support and love they deserve by default.

Much love,
