Hey there,
It sounds like you are feeling a bit lost at the moment because you don't have a connection with the people supporting you and I can see how that would concern you

.
I have never had DBT but if they were more detached my guess would be because it was designed for Borderline Personality Disorder and people with the condition usually have attachment issues (amongst other things) and maybe they find it better to take a step back and remain objective. However this is only a guess as to why they could be but it probably ust depends on each therapist and maybe with time you will feel a stronger connection to your T?
