What will happen if I get my goldfish mad??? I am a little afraid?

Yah see, my goldfish is very violent and hates me with all of it's........ Well I am going to say fins because I know he doesn't have a heart. Anyway, I keep Goldenburg occupied all of the time!! I read him his favorite book, 1 fish 2 fish red fish, blue fish, I play go fish with him, I even wrote him a song on the banjo!!!!!!!! I am really afraid he will beat me up or drown me while I am sleeping. What should I do!!!!!! If I try to sell him, he will fly back to me and I might get hurt if he finds me!!!!! What should I do!!
