I read this book a few years ago, i believe it had a blue and green slushie looking cover (it was a library hardcover) that might've had little skulls in it. the main girl, highschool age, dies somehow. her ex friend(guy) or something family are morticians, so he goes to help prepare her body, but she wakes up. He hides her and saves her because she is scared to be dead and doesn't know what to do because her body is rotting. nothing seems to taste right for her. i think at the end she goes off or accepts it and they rebury her???

if this isn't a book it has to be a weird fever dream, but i remember if being an amazing book if anyone can help me find it. i read it when i was in middle school, and i would love to check it out again.
