Who feels the way I feel?

AU. One-shot. Rated T for teen suicidal themes and cursing. Bubbline. Marceline and Bonnibel were fine. Their grades, friendships and even relationship too. But when Marceline becomes exceedingly distant due to reason unknown, everything falls apart. Now Bonnibel races to find the truth and keep the worst from happening. R & R plz and future apology for the extreme sad feels :(
