hey. DBT has been shown to be the most effective treatment for BPD so it is great that you are doing it :-)
i did one year of DBT. I remember that we went through the skills 2x over the course of the year. i remember that a lot of it didn't sink in until the second run through. i remember that even then i still felt like i was missing a part of it lol.
i used to read a lot about BPD to try and understand what was supposed to be wrong with me...
there is a variety of material out there, and i noticed that it varies a lot in terms of how understanding vs judgemental it is. some of the stuff... is simply hurtful, there is no other way to say that.
the most helpful to me...
was to read Linehan's treatment manuel.

yes it is expensive, but you should be able to find it (or order it in) from your local library. i cried and cried my way through it. it helped me understand a lot about myself. it also helped me understand what my therapist was trying to do. it also helped me understand the rationale for the treatment. it also helped me understand the skills.
did you get handouts for the skills part of the course? IMO this is worth getting (and photocopying) too:

i found it helpful to have the handouts from there (which summarise the skills). but i found it EVEN MORE helpful to have the little blurb that introduced the handouts where they talked about the rationalisation / justification for the skills. they talked a bit about problems people may have with understanding the skills and applying the skills and so forth. i got that and photocopied the sections (that were meant to be for the skills trainers) and that really helped me understand the skills, and that really helped me do the skills too.
i also noticed this:

i have no idea what it is like... but it may be worth a look...
