“What does dialectical behavioral therapy mean?”

Namaste,  As you have not explained I am curious about the reason you want to know about DBT and how you heard about it.  Briefly, it helps a client apply Mindfulness, Distress Tolerance, Emotional Regulation, and Interpersonal skills to a variety of issues such as anxiety, depression, addictions, self-sabotaging, self-harm, etc. In case you are dealing with any of these issues I would urge you to seek immediate help. Take care and remain safe.
