I agree with espresso, jean.
DBT was very helpful to me...but it takes time to become comfortable enough to share little bits of yourself here & there, in group DBT. Some relaxation exercises are more effective and comfortable than others. I really loved rubbing rocks, or looking at leaves, and HATED deep breathing exercises. Others were the opposite of me. To each his or her own.
Give yourself some time to adjust to DBT. Some leaders are definitely better than others! Hopefully, the 2 that your currently have will start to "ring bells" (make sense) very soon for you. Best wishes!
