My Rabbit ate a plastic ziploc bag and Im scared because she wasn't acting right What do I do?

I have a Babby rabbit named Ebony she is 10 weeks and 4 days old well brought her to school for a week for an animal science project. I was going to train her tricks, so far she's got sit up pretty down flat but today when I went to go check on her. I notticed that she had gotten a hold of the plastick ziploc bag I left by her cage and she ate the sealing part of it.But she didnt eat the glider thing that closes it I looked in her cage and I saw bitts of red plastic from the bag I told my teacher and she said "I dont think it will do anything to her, It would probably just make her constipated" Then I had to go to my next cl ,and we had to go to the library The librarian absolutely addored her and let her run around in a room with me and a few of my friends. I told her what Ebony did and she was shocked so I got on the computer to look up a few things about it, but nothing really gave me enoufe Information. I then had to go to my Animal Science cl for my next period. I brought her into another room just me and her so I could train her. well she wasnt really participating like she had been (( It didnt help that other kids went i thier and distracted her more)) so I took her in the other room. Well she peed and i went to clean it up and while i was cleaning it up I saw something on the table that looked like a slug and felt like a slug but it wasnt a slug it was her droppings. and knew that wasnt right then dhe wouldnt listen at all I need help can somebody tell me what to do?
