Is it possible to p a course with a decent mark without attending lectures?

My prof did something behind my back that really traumatized and ashamed to go back to his cl. Talking/emailing him is out of the question bc I feel betrayed and his coldless action and personality make me unable to trust him. Talking to a counsellor does not help me overcome this. I don't value their opinions and I don't know them and I don't trust him or a counsellor. I don't want sympathy. I just want to get things down and forget the incident of feeling betrayed. Every time I look at his ignment, I can't forget how he hurt me. I hate him and never want to see him. I have no rights in the matter bc I am a student and he's the teacher who has the authority to do whatever he sees fit. I feel violated but it's not as if he did something criminally offense. He just went behind my back without discussing me first, he called the police on me thinking I seem suicidal. I admit I have problems at home and my parents are ill but the police basic treated me like a criminal.
