Very poorly penny, help needed asap

[sarahhhh]

Hi all,
My hamster Penny has suddenly become ill tonight. She's not very aware of her surroundings, ears flat back, eyes bulging, falling over and slow and sluggish.
I've rang my vets and they've said there's no exotic vets on tonight. They said there's one tomorrow but when I asked if I could come in at 8am and see her ASAP but she stated she would not be consulting so I would have to "wait until she finds a minute".
Penny is very anxious, she hates people, including me. Despite her sluggish state, she still managed to bite me. I leave her alone, just making sure she has run time, food, water, a large cage and clean bedding. I don't feel a vets is the best environment for her to wait for an undetermined amount of time.
Basically, has anyone had anything similar happen to them and their pets? Any advice on what to do tomorrow as vets around here don't take you unless you're registered?
