Dear Hope,
I can remember coming completely undone and upset by bad therapists.
Most of the time, I knew that the problem was the therapist and not me. But I still got upset.

Are you doing this DBT in a group setting? Is the group part of what is throwing you off? -- I hate groups by the way.

At any rate, you don't have to do this.
And even if you do this, you don't have to do it now. You can do it some other time in the distant future if you are ready to try it again.
Or you can buy a few workbooks on DBT and work through some exercises yourself.

DBT happens to be popular among the therapy people right now. That does not mean that it is a miracle.
And it does not mean that it works for everyone.

Take it easy on yourself.
You are the same person you were a few weeks ago. Don't let the bad experience of DBT throw you off.

Take care of yourself. You will be all right.

M.
