Hi CherryGash,
I can relate. My perfectionism isn't pretty ~ it only hurts, yet I hold tightly onto this tendency.
My T's style isn't CBT. He uses a variety of all styles. Depending upon what we're talking about, he may lean towards some CBT techniques. Another time, he uses other styles. That seems to work well for me. As there are things from each style of therapy that I can appreciate, but that doesn't make me lean towards any one particular style of therpay.
Whatever you believe is the answer ~ DBT, CBT, one-to-one... ~ will work for you. That is one benefit to being a perfectionist. When we commit to something, we hold true to the very end! That's the lighter side of being a perfectionist
