You are forgetting one important detail: It is not true that the only time we really saw an extreme personality change was as Lacey. She also had an extreme personality change after Hook shot her and she fell over the town line. She reverted back to her former, cursed self, becoming extremely afraid, prone to panic attacks (she even had to be sedated, at one point) etc., with no memories. This was the cursed Belle, the woman she was during the curse.
