Is my 8 week old bunny going to die? please read im so scared. im sorry its sorta long.?

tonight my mother adopted an eight week old bunny, she ate fresh hay and did not eat any pellets. she was perfectly fine at the pet shop where my older sister works. but once we brought her home she was kind of nervous and after two or three hours when we put her in her newly set up cage she layed flat out of her stomach and spread all of her legs. Her head was up but her ears were not flat on her head which usually occurs in heat stress or heat stroke. my mother took her out and placed her on our carpet so she could run around. her stomach then became very bloated and hard, (a sign of early GI status) her stomach began convulsing which i know is not a good sign at all. we soaked her in tempat water and then sprinkled it along her spine and soaked her ears, tail, feet, stomach and head. to try to cool her down. especially her ears. now she is crouched and no longer on her stomach. please dont just say take her to the nearest vet immediatly, we are already on our way. I would just like to know if she is going to p like our other two bunnies or if she might make it since it is eitther early signs of heatstroke or G.I status. they are leaving for the vet right now, no worries. I just feel so bad for her. my sister is holding her stomach up to her ear, she just said that her stomach is gurgling. I am only fourteen but i know what is going on, this has happened twice before, but we take very good care of all of our animals. for the very nice and wonderful person who answers this honestly i will award you with 10 points, thank you so much,, sorry for asking this twice im just really freaking out. <3 thank you so much , mel
