"I wonder why therapists seem to have little regard for DBT?"

Good question.

I started do-it-yourself DBT seriously about a month or so ago, and my partner is already saying that there is a 'signficant change' with me. I'm not sure what that means and I am trying to not have too hopeful of thinking: I don't want to set myself up for failure.

But...what I'm doing is the DBT workbook found here (similar to Linehan's)
http://www.amazon.com/Dialectical-Be...s=dbt+workbook
^Along with keeping notes and a journal about my successes and failures with it.
There is a free DBT Yahoo group/class that I joined (thanks to Maranara)
I am doing a lot of meditation (generally learned from Buddhist resources)
I am talking a lot with others about this disorder (here in the forums and in chat) and am finding it helpful and supportive.
There is also a DBT skills chat on Saturdays here at PC at 1pm EST to learn more about DBT and talk about it.

I say that a person can only benefit from DBT. As powertools mentioned: "It is beneficial to anyone regardless if they have a mental illness or not. "

You're not alone. Thank you for sharing your experiences, come vent anytime you want, we support you .
