Yes.

My PTSD comes nearly entirely from family, and it is hard to break because as children we are prone to always believe what are parents say: we blame ourselves. Our view of the world is very simple when we are young, and it carries over into adult life...

It takes a while to really recover, sometimes years. The best bet is to find a therapist you can relate to and feel a genuine connection with and work with them... You'll begin to trust them and see that they are competent, if the therapist is a good match...

Also, have a thought diary and challenge every thought of self-hate that you can recognize.

Personally, I have an internationally renowned therapist whom I see 5 days a week, but on the side I do Acceptance Commitment Therapy and thought challenging. There are plenty of books and apps for these things. You can do these things on your own without the help of a therapist. The role of a therapist is to have someone who is always there to listen, because we never had this when we were growing up... You don't have to worry about being "too much" or "not good enough" for your therapist (at least rationally, but you still will hold onto these beliefs for a while).

I can write more if you'd like, recommend some resources, share what I do and tell others to do...
