That being said, breaking middos is a lifelong job, and you must not get discouraged or feel overly guilty when you express a bad middah; it’s for this reason that most bad middos aren’t flat out assur, because we’re not always in control of them, and Hashem knows that – but we are in control of the actions that those middos lead to, such as saying lashon hora. But if not doing so makes you feel bottled up, it needs to be worked on with mussar heavily, as above, because it’s not mentally healthy to bottle things up
