Help with a sickly hamster?

My teddy bear hamster suddenly became sick today. I tried to wake her up and she just flumped over. Then I realized that she was breathing really hard with her mouth open and her eyes are glued shut. I gave her a quick wipe with a warm towel to open her eyes up and she gradually regained composure. She is still breathing hard and now she is trying to walk around and when she tries, sometimes her bottom half flips over. She is 2 yrs old. I recently changed to pine bedding as well from the other softer bedding. Oh and she is still eating and drinking fine. Any help is appreciated!
