DBT teaches you to identify levels of pain, as there are some people who tend to experience it disproportionately to the situation. Most people can navigate this stuff naturally - there is a lot of gray area and they do it unconsciously - they are hard wired to respond a certain, appropriate way. Like I said it's just interpersonal skills that are usually modeled to us as children, depending on the upbringing. If we weren't in a family that taught us then these skills have to be taught (which I'll admit can sound condescending to some people). People who have trouble self regulating and who experience things as all good or all bad can have a lot of difficulty maintaining good relationships and DBT is great for helping people find balance. Pain doesn't go away but you can learn to accept it or continue to suffer. It's very difficult and takes a long time to master this stuff. But for those that need it and are willing to try, it really helps them improve their quality of life.
