DBT I think was the style of therapy used on account of the (borderline) personality disorder possibility. It may not be appropriate for the depression you yourself are going through. CBT I would suggest is better for your own mental health. SImilar yes, but not the same. CBT recognizes that depression and anxiety stem mostly from negative core beliefs we have. The aim is to learn to recognize them, meet them head on and relearn new thoughts/behavior.

A good start is to consider the 10 cognitive distortions. Question how legitimate they are and adjust your behaviour accordingly.
