My old rabbit I had, Spring use to be mean like that, and bit your hand real hard, and make it bleed. I don't have any advice but I know what you mean. I gave her away though, because she hardly got any exercise, and the lady would give her a way better life, she was rabbit crazy and had like 25 rabbits. (also a big yard for the bunny to go, and huge houses) It was really hard the first few days I keep crying, because I missed her, but after a few days I realized she was having a better life. (the lady even sent me pictures) Good luck!
