What worth do I have if not protected or fought for?

My ex therapist's scars are still open, also because he chose not to disclose our sessions and leave it all open. No good ending nor bad. Just to let him know through SMS and end it that way. I insisted on a closure and got none. I insisted his anger really hurt me and emotionally ranted that he's not perfect and gaslighted me by saying that I love being angry at because my father was this way.
I really insisted my mother take a stand for me, because my father is a useless piece of rock and my mother won't admit it.
So she did and I saw it was hard for her. She told my ex therapist about how she FELT about him and mostly me. It was always about the FELT and FEEL. I told her and she insisted otherwise, that it's unbelievable how uncomfortable she was and how submissive she had to be to tell my ex therapist what had to be told. The best she could tell him is "If my son felt so bad because of all this, then it has to mean something" (she wasn't strong enough to say "it has to do with you", but neither would I be. And that's exactly the problem with him). To that, he replied with a moment of silence and his other non-apologetic responses. The most close he got to, and was repetitions of what he'd tell me, is "I'm sorry you felt this way", or "The last thing I wanted to do is make you feel this way". He also said "He has allot of anger on me" when he talked to my mother. From the pronouncing of his words, he obliterates all responsibility from himself and puts it all on me.
I also feel he's made me dependent on him, because he's always inside me and have no way to get rid of him. I always feel that in order for me to make improvement, I have to come to him and no one else.

And with that, I will add that I posted some angry posts about things which anger me and got no replies. It's either a sign that all my rantings are right and just, or that my case is truly hopeless.

How can I believe the world is improving and we're reaching an area of greatness, if (short sensitive rabbit-hole data)
