Those who use the Vipassana style of insight or "mindfulness" meditation come to see in time that all emotions, sensations and feelings are impermanent: They arise, become evident, dissipate and disappear in time. Moreover, they come to see that when emotions, sensations and feelings are allowed to be *as* they are *when* they are, the coming and going of them is more rapid and less discomfiting and agitating.
Virtually everyone I have ever seen who has anxiety or depression has a case of "emotional constipation" that is the result of attempting to deny or resist the direct, conscious, mindful experience -- and *digestion* -- of their shame, guilt, worry, remorse, regret, frustration, resentment, anger or agitation. They do so because they were instructed, trained, conditioned, socialized, habituated and normalized as children to suppress and deny their feelings to avoid being insulted, criticized, judged, embarrassed, humiliated, ridiculed, persecuted, picked on, bullied, scapegoated, and/or otherwise abused by their parents, their older siblings, their playmates or others in the first few years of life. The result of such habituated suppression over 15 or 20 years is ultimately severe depression or "emotional incontinence" ...or a swinging back and forth that looks just like borderline personality disorder.
Mindfulness-Based Cognitive Therapy (MBCT), Dialectical Behavior Therapy (DBT), Acceptance & Commitment Therapy (ACT), Mind-Body Bridging Therapy (MBBT) and Mindfulness-Based Stress Reduction (MBSR) were designed to be "emotional emetics" for those with emotional constipation and incontinence. Likewise the 10 StEPs of Emotion Processing, which is a combination of Vipassana mindfulness meditation with the principles of General Semantics.
All of them teach patients how to "be with what *is* in relationship," which is to simply observe without resistance or suppression the coming and going of emotions, sensations and feelings along with the ideas, evaluations, appraisals and judgments we have *about* them. Just sensing them so that they can course through the mental digestive system and be discharged.
