Everything you discuss is confidential between you and the counsellor or psychotherapist. There can be certain legal exceptions and the practitioner should clarify this with you prior to the establishment of any agreed contract for working.
You may have specific queries about confidentiality depending on the format of the therapy. For example, with online counselling, you may wish to ask the following questions to your therapist:
- Are the notes from therapy protected by passwords and encrypted?
- Are printouts held in a secure cabinet?
- What happens when there are technical problems?
