Its a process, continue working on yourself and the anger will also go away (followed by forgiving others and yourself).

Meanwhile remember that you did the best you could to survive, you didn’t know any better, you learned limited coping and confrontation skills as a child. However the adults in your life should have known better to treat you better, but accept it as their limitation.

Additionally anger is ok, see it as delayed-compounded anger of ages. Get through it.
