Hey @Gwynn I did two rounds of DBT over about 18 months. I was very reluctant to do it but it was not because of the horrible experience you described - my biggest issue was being in a group of people. It took me nearly the whole first round to be present at the sessions and I also found the weekly forms difficult @Mazarita. What I did find was at the end of the second round I could look back on those and see how far I had come - so that ended up being valuable for me.
I did not get a lot out of the first round - it was more about surviving each session - but by the second round I could start taking things in and working on different aspects of the course each week ...and that did help. I did DBT in a group - followed up by a session each week with my pdoc so it was very different than doing it with just one person. Our facilitator was very good - and very skilled at both delivering the course as well as keeping everyone safe and on track ...and that is importtant in such a setting. Anything that came up for us or any triggers we encountered we could then discuss/work through with our pdocs after the session - and honestly that was absolutely the difference in me getting through. I often came away from group initially feeling like I never wanted to go back but we talked through that in the follow up sessions and my pdoc continued to encourage me to go ...and I am glad she did.
I will say that not everyone gets the same benefit from DBT as I did and for some it is not the right time to do it either. We had one member that began the course but was quite clearly in distress each week and that really affected the whole group. As a result she was encouraged to work with her pdoc further and return at a later stage when she was more able to cope. It was necessary for both her and the group.
I do not believe DBT is for everyone and you have to be both willing and able to do the work. The only advice I can give is to talk to your facilitator of the class, let them know your concerns and if the fit is not right for you after a few weeks then discuss that with them again.
Will you be having follow up sessions with your psychologist? If so will that be close to the time of your DBT class? I found having those follow up sessions on the same day imperative to get through and continue each week.
Happy to answer any questions you have and walk through this with you - whatever you decide
