I tried DBT on my own and it is very, very hard to stick with under those circumstances. My life saver has been mindfulness and meditation, which is where a lot if the DBT concepts originally came from. One good place to explore for that, and DBT as well is DBT Self Help. On that site is the entire DBT curriculum, but, like I said, you need feedback and such and I've been unable to stick with it on my own. Also on that site, however, is a section labeled "instant Mindfulness". There are a handful of short, guided meditations that I've found very helpful. One warning: do not expect to find instant relief no matter what you do. It just doesn't work that way, but I firmly believe that mindfulness and meditation has saved my life several times over. I'm willing to give additional resources to anyone who is interested.
