Mindfulness is the basis of both DBT and meditation, which are two of the most prevalent ways to combat BPD. Basically, as BPD's but it's actually something most people do most of the time, we don't live in the present moment. We dwell on the past or worry about the future (as what you're doing when you're scared of going "back" to how you were before). What mindfulness does is tries to get us to "live in the moment". Live for the present without dwelling on those things. It DOES work, but it also requires A LOT of work. I firmly believe if it wasn't for meditation I would have been admitted several weeks ago.

What a lot of people tend to do with this stuff is they half-heartedly try it once or twice, proclaim that it doesn't work, like an old appliance, and discard it. It takes a while to understand what to do and I firmly believe that most of us can benefit if we're willing to keep and open mind and do the work.

www.dbtselfhelp.com is a good place to start and look. You can go to a section called "Instant Mindfulness" for some short, self-guided meditations and it also has comprehensive DBT lessons which I've started doing again.

Of course, there's other methods to come to mindfulness. Some are able to figure it out on their own and don't necessarily call it such... It works regardless.
