Behavior issues..

Does anyone know anything about bunnies? I got a rabbit for my birthday which was September 27th. At first she listened she even ran into her cage when I tapped the door and she actually came up to me, now she is distant, she tries to bite, and she hates being picked up...its extremely difficult trying to get her back into her cage when I need to leave or she is being bad she'll run away and kick her feet somtimes she'll squirm so much she ends hurting herself or me...does anyone have any tips or advice on how to fix this or start to?
