I don't know if I exactly understood your question. Were you asking if your counselor stops working as a counselor whether she still has to maintain confidentiality? I don't know, I always assumed that therapists have to maintain confidentiality indefinitely. I suppose the thing that enforces that is that they could loose their license and their career if they get caught breaking confidentiality. But I can think of two questions-
1. Is your therapist/counselor licensed by some professional organization that guarantees confidentiality? Since you called her a counselor, I guess she's not a regular psychologist or social worker?
2. If any therapist quits their profession, I wonder what is left to enforce confidentiality? Does anyone know? Could they get sued or something if they blatantly broke confidentiality, even after they had stopped being a therapist?
