A few other things that can be helpful:
1. Remembering that whatever happens is from Hashem and is good and nothing anyone can does can change that. Even if it seems like someone else harmed you, they can’t do anything to you. Whatever happened to you was from Hashem and not from them.
2. Try to figure out where they were coming from and why they may have done what they did. In other words, try to be “dan l’kaf zchus.”
Whether or not, the above 2 things are shayich for you depends on you and on the situation. If you feel that you can’t think that way and pushing yourself makes things worse, then don’t. I know that sometimes I need to work more on acknowledging my feelings and not on focusing on the above 2 things, and trying too hard just makes things worse. But if you are able to do them, then it’s kidai.
