It does sound like she is on the way to the bridge. She is quite elderly for a hamster at 2 and it sounds like she has a pyometra which is a womb infection. Once they cannot maintain their temperature they are really very ill. I would tuck her in warm in her nest and see how she is later. If she is unable to pass on her own then get in touch with the vets as you may need to help her on her way. I'm so sorry.
