Spaz the rabbit

I'm feeling like such a bad rabbit owner. :( I went to check on my rabbits this morning and Spaz has fly strike (ie, open wound near her tail with flies, etc). I went ahead and took her out of her cage, bathed her with baby shampoo and cleaned her up as good as I could, treated her with antibiotic ointment, scrubbed her cage down, then sprayed her with insect repellant before putting her back in. From what I've read it's not a good situation. I'm just feeling sick to my stomach....
