She has head tilt. It's really not bad. It depends on the cause, if its an infection, she needs antibiotics. Self diagnosis' can be less reliable than taking her to the vet, and you may have to go through several different kinds of medication before one of them works, so it may cost more, too.
Google "Head Tilt in Rabbits" and it'll come up with all the different causes and treatments. I know I'm late, but unless it was an infection, she won't die.
BTW the spinning is from her trying to regain balance because her head is sideways, not from dying.
I hope she's better!
