Can someone help me with nightmeares and reacoring thoughts?

hi, i was ually abused from a baby till 14 by my father. i have had over ten years of counsling. i never turned to drugs or any form of anything to take away the pain. i went to cousling for 10 years strait. a few years back i went threough a ruff time and was diognosed with depression anxiety and pannic attacks, this has subsided now thanks to medication and changeing life style. Now i get haunted with night mares but not as much as reoccuring thoughts of the abuse, little things trigger it off and it is like reliving it all over again feelings and all. it is making me sad, sick and hatred towards him. i get upset and want to go to his home and just abuse him. he also has told everyone that he went to jail because he stabbed someone (wich he went to jail because of the abuse towards me) some have found out about this and he says it was a one off thing and puts my mother down. im now 30 and just had enough what can i do to stop my thoughts? and reliving the situation in my mind?
