Is it normal that i'm this mad at my father?

I have allways had a close relationship with my father. but resently, we were on a trip to turkey together, and he drank alot. he was a real jerk sometimes. and now I just see him as disgusting... and I feel like I'm better off without him. we have never lived together, becouse mom and dad are divorsed. but I was so mad at him that I wanted him to fall off the balcony or something.
on top of that, he started to cry one day, becouse I was crying, and I felt really uncomfortable that a grown up like him started to cry so much becouse of me. what can I do? is it normal to feel this way?
