One way my T helps me is by pointing out the dysfunctional interpersonal crap I do (e.g. “punishing” someone I’m upset with by retreating from them and sulking privately and forever holding resentment) and helping me find less-stupid ways of handling things (e.g. waiting until I am calm, talking to the person about what happened that made me upset, and making a plan for navigating similar issues in the future).
