If her nose is clogged, it would be because of an injury obstructing the nasal passage in some way, like from bleeding into the nasal passage or tissue swelling obstructing the nasal passage.
I can't say if she'll be ok. Only a vet can determine this. But if she is having real difficulty breathing, particularly if she is opening her mouth at all to try and breath or raising her nose into the air and struggling to get a breath, then it can't wait, as respiratory distress is an emergency. If it's an emergency, then you'll need to phone around to emergency vet clinics to see if you can find one with an exotics vet on shift.
If she seems to be ok breathing but isn't back to normal behavior wise and eating by morning, I would phone a rabbit vet first thing. Tell them about her injury and that she isn't eating. She will need to be seen tomorrow, as a rabbit not eating needs to be seen as an emergency.
