i think it's "bear"; she can't be away of us, she can't deal with this idea. she's asking herself: "if FAME hav an IV, could I bear being away from you?"; in other words: if she could """consume""" FAME like a drug, would she be able to be away of us?
so "bear" it's the perfect word to that, as long "bear" is a synonym to "support"/"tolerate the idea"/etc
