I've had CBT and it wasn't effective for me. I didn't hate it; my reaction was more that this therapy is something that I have already been able to figure out by observing myself over my lifetime and therefore it can't be the solution for my problems.
That's not entirely true though, because there is what's called willfulness. When I felt that the therapeutic structure was ho-hum and the information offered was too elementary, I was then unwilling to do the practices associated with CBT. My emotions were hopelessness and abandonment, as I got my CBT referrals through hospital stays and I felt that this was the best available help for a person like me. This is pre-diagnosis for me. The adage goes: "if you see hoofprints, think horses before zebras" and I was still in my horses days. Doctors were treating the most common options, and the most commonly successful treatment is CBT.
But anyway, it was not a fit for myself and my diagnoses, and I was very willful about it. I would not engage in any of the practices associated with changing the emotion-thought-behaviour cycle because I was stuck in thoughts of "this stuff is KINDERGARTEN!" It's worth noting that any therapeutic structure feels like kindergarten if you are not willing to practice the material. By the way, that's the opposite of willful. Willing.
To compound those difficulties, my emotional reaction to the situation was incredibly strong and I did not have the skills to cope with that reaction at the time as I had gotten no appropriate diagnosis or treatment. I'm really trying to avoid saying dumb shit like "it works if you work it" but I am regretting that because it would have been much shorter to just say that.
Taking a compassionate view of myself, this pattern of thinking is best viewed as an obstacle to myself accessing treatment rather than as a failure of CBT, or of myself. I was a patient whose reaction to treatment was to scoff, and I needed additional coping skills and a trusting connection and just lots and lots of things needed to be true for therapy to have an effect on me.
Therefore, the additional structure of DBT and its inclusion of skills to handle extremes of emotion became the thing to try.
Also, I was diagnosed with BPD and therefore gained access to publicly-funded DBT, which I did not gain access to due to waitlists and pathetically small seat numbers. I paid out of pocket, which is bullshit. And, that was the program to help me.
CBT is baked into DBT, by the way. Hence the similarity in acronym. It's not taught the same way it is in CBT, but these programs are effective when they are compatible with a patient, and the patient is willing to invest, etc etc.
I don't know what it's like to have a condition that responds directly to medication but I gotta say as a patient whose most effective treatments are therapy, I feel a little envious.
