I have anger towards a professor? advice

I went to a university this summer for graduate school. This professor was disrespectful towards me and even lied and manipulated things she said to me. I never had an issue with a teacher before this extreme. I was later dismissed from the program at the end of the summer. I believe because of this professor who was immature. She was adjunct and did not have a PHD. I think I was dismissed because I was making complaints on the department and they did not like that. I hold anger towards the professor because I was treated poorly by her and the department. Even though, I am in another program at another university doing better. I still hold anger the way I was treated. I have emails where this professor tried to make me do more work than other students.advice? I have made complaints on the professor outside of the university. Please advise me something helpful for this situation?
