How do you deal with anger after being wronged by a doctor?

I've considering opening up a medical malpractice case or at the least filing a formal complaint.

Yet I know that won't really make the anger go away.

Ultimately it is like my lack of responsibility for the circumstances of choosing the doctor seems like what ended up with the doctor wronging me(us), but it is like I was wrong in expecting a doctor to have their patient's interest at heart and I am having trouble reconciling this.

Should I do nothing towards them? The doctor has not apologized for their actions and likely will not.

Yes I do also have compassion for the doctor as the doctor is incredibly selfish and self absorbed and self centered. But I even find myself getting angry at myself too for not listening to my intuition and finding another doctor before it was too late, the doctor seemed friendly and caring at first, but ended up being very deceptive.

I'm stuck in a loop of trying to let the anger go and accept what happened, and wanting some recourse for being wronged.

I read this thread, https://www.reddit.com/r/Buddhism/comments/4kjn9b/is_anger_ever_justified/, but I find myself still at odds.
