Maybe DBT isn't for you? For me personally, I can't stand DBT. Many of the concepts just don't help. Don't get me wrong, I know that DBT helps many people, and I am not discouraging you from doing DBT, but since you say you're struggling with the concepts, maybe another type of therapy like CBT would be better?

I've had a number of therapists and people tell me I needed DBT because I've been so symptomatic in the past. I tried DBT a number of times but I only ended up in a worse place. However, when I tried straight CBT, everything just clicked right away. (I'm in love with CBT and recommend it highly!) CBT worked a million times better for me than DBT. (But of course, we're all different.....and yes, my emotions were all over the place and of course, because of that, the automatic recommendation was DBT....but as I said before, CBT is what helps me the most.)
