Hamster won't open eyes and wet tummy!

[bernald]

Pls help! My dwarf hamster is over 1 year old now and she has never been sick before, but just today, she started to show some weird signs: she won't open her eyes even when she's awake and go around (she usually just sleep all day, occasionally move to a new spot to continue doing so), i tried to wipe away the eye's "dust" with wet tissue but it didn't help, and she seems less energetic, less responsive to enviromental factor (like when i accidentally make a loud noise, she'd wake up, but today she just doesn't seem to be bothered, even when i lightly touched her). I also noticed that yesterday and the day before that she didn't seem to care about the food i gave her but was still very active (like running on the wheel and stuffs) and she seems to have yellow wet tummy (which could just be her urine), doesn't have a wet tail. I did gave her a piece of banana and cherry on the last 2 days (this is not a usual thing, only occasionally), I have read that it can cause diarrhea, but since she's also has been peeing and pooping less than usual (like barely) these couple of days, i'm guessing that's not the case! And the vets are out of questions bc there are no vets that treat hamsters where i live! Pls help, i really don't wanna lose her!
