Enemies

Does anyone have any advice on dealing with people you think are bad and dont like/not obsessing over with hatred? Due to my background of abuse, people being cruel was usually dangerous so and I developed the mentality of having to fight them and dominate them to survive.

However, i am not in that environment anymore but still have those responses of hate instead of dislike and tend to obsess about how much i hate them and how much i want to get revenge even if theyre not bothering me currently.

Any advice will be appreciated, thank you.
