Acceptance and Commitment Therapy (ACT) uses a mix of acceptance, mindfulness, and behavior change strategies to improve mental wellbeing and increase psychological flexibility. ACT is a very experiential type of therapy that uses in-session exercises, metaphor, language, and physical movement to focus on living a valued life instead of getting stuck in needing to "get rid" of suffering.
One of the biggest skills gained through ACT is listening to your own self-talk—the way you verbalize and understand things like past trauma, physical limitations, past relationships, or anything else on your plate. And, then with that understanding, choosing how to move through it—either by change or by acceptance.
