The last thing I want to do is sit in my therapists office while he makes excuses for her behavior yet again. He gave me a book to read so that I could see her as a person and not just a parent.
My therapist did the same thing. Every time I talked about my mom and what a total bitch/c*nt/horrible person she was/is, it seemed like he was making excuses for her. It really pissed me off and made me feel like the way I felt wasn't important.
Now, a year later, I can see her as a person and see that she has/had her own issues. It doesn't excuse the things she did or didn't do, but it has taken away alot of the anger to realize she was just as f*cked up as I am....maybe more.
It's hard to see past the anger and even harder to ever think you may see past it, but once you do, it makes a huge difference.So, I don't think your T. is wrong is what he's doing. I think he's trying to help you, not just piss you off.
