On the positive side, my T has said "competent." Which sounds negative, but she's more like, "You're so competent, why wouldn't you think you could handle x?" On the more negative side, "hypervigilant," like I notice little things that others wouldn't, mostly about other people (she seems to mean it in a negative way and reflective of my OCD and anxiety).

For marriage counselor, first one that popped into my head was "strong" as in, "You're stronger than you think you are."
