I'm seriously considering dropping out, as I can't see the purpose. 

So, I'm in a public system BPD treatment center. It's designed to divert people from the emergency department and psych hospital. The center offers either 6 months DBT for 5 hours per week (incl group), or 12 month 1 hour per week CM therapy. At my assessment the psychologist agreed that I don't have a skills problem (my uni degree has covered most of the DBT skills as professional skills) so would benefit more from CM. 

Now that I'm a few weeks in, I don't see the point. What is it supposed to achieve? The literature talks about the vague goal of repairing the psyche, but I don't even know what that's supposed to mean.

What's the benefit of this therapy over a diary?
