Hello, I'm so sorry to hear your hamster is not feeling well. The photo looks like she may have some diarrhea, which may help to explain why she has been lifting her bum up (tender) and has been lethargic. Her increased breathing rate may be a sign of pain. Unfortunately, two years old is considered elderly for a hamster so we also need to think about cancer as a possible cause as well. I would take her to a hamster-friendly vet as soon as possible. They may be able pinpoint a cause, and at least to provide medication to help with the diarrhea and pain, and fluids to help rehydrate her. I hope this helps.
