Welcome to RO, by the way! I'm sorry you found us under troubling circumstances, but I hope you stick around and check out all the other great info our community has to offer.
JBun always gives great advice, so I would follow what she suggested and get your bunny to the vet as soon as you're able to (make sure to tell your vet what at-home remedies you've already used, how often and whether or not you saw improvement when using them).
