Would you consider a self-directed DBT program. There are many fine workbooks out there.

I have one comment on them however. It is really is to both NOT read ahead and gloss over the homework. It is really important to work through the material slowly and actually do the homework - on a daily basis. Most are designed to take about 12 weeks to complete. Then of course you need to maintain the work afterwards.

Please don't be put off by the title but "CBT for Dummies" was a great book and I am assuming then the DBT version will be similarly awesome. They are set up in a journal format and thus easier to stick to than the other workbooks out there.
