Acceptance and Commitment Therapy (ACT)
"Acceptance and Commitment Therapy (ACT) encourages people to embrace their thoughts and feelings rather than fighting or feeling guilty for them.
ACT develops psychological flexibility and is a form of behavioural therapy that combines mindfulness skills with the practice of self-acceptance. When aiming to be more accepting of your thoughts and feelings, commitment plays a key role. In the case of ACT, you commit to facing the problem head-on rather than avoiding your stresses. Imagine committing to actions that help you facilitate your experience and embrace any challenge."
