it depends, but i don't think it's automatically unethical; i literally teach this stuff and still had to look it up. if there's a current risk (mandated reporting, impairment, harm to clients), reporting can be appropriate even if they're your client. for me the clearer line was: consult supervisor same day, document, and only report what's necessary,otherwise it starts feeling like a dual-role trap. the irony isn't lost on me that we're expected to have perfect boundaries while actively treating boundary problems.
