I have a rabbit, and I'm going to tell you if your mom isn't willing to put in a LOT OF WORK and doesn't possess A LOT OF PATIENCE, you don't want a young, adolescent rabbit. Once they hit their teenage phase, they will destroy your place and you'll be wondering why the hell you got one, if it's going to be an inside house rabbit.
Adopt an adult. They'll be fixed and they make much better pets when they are fixed. They're not hard to litter box train, but rabbits chew, and they can eat your carpet, base board, furniture legs, and most dangerously, your electrical cords which could kill them or start a house fire.
There's a ton of info here for caring for pet rabbits:
