Make sure she is drinking. You don't have to insist on her eating just yet, but keeping her from becoming dehydrated is really important. With the blood loss, giving her some electrolytes like Agri-Labs Electrolytes Plus, Aqua-Lyte Blue, or Aqua-Vite probably wouldn't hurt, but mostly make sure she has hay and water within reach so she doesn't have to move to get them.
@tambayo 's suggestion of a little extra heat for a while is good (not hot, just give her body a break so it can use its energy to heal rather than maintain its temperature).
Watch her when she moves or you gently handle her, and be alert for other injuries. It could be that a predator (rat, weasel, etc.) attacked her, or that she got her ear stuck somehow and thrashed around trying to get free.
She sounds like whatever made her bleed also traumatized her pretty thoroughly. I'd agree with keeping her inside for a while in a calm, quiet place. I wouldn't bother with any ointment even if you find the wound. Rabbits just lick ointment off. If her body rallies, she'll heal. A treat, like greens or a little apple or banana, might tempt her to keep hanging in there. Talking to her in a calm voice, and petting her if she likes being pet, can also do wonders. Watch for comfort movements - it's a good sign when a rabbit is willing to groom itself.
