All counsellors and psychotherapists abide by a professional code of ethics, set by our membership bodies (in my case the BACP), and this includes confidentiality. I understand and respect the need for complete privacy and discretion when looking at sensitive issues.
However, if it seems there is a high risk of serious harm to yourself or someone else, then I will usually discuss that further with you, to see if anyone else might need to be informed (such as your GP).
If you tell me something that I am required to divulge under oath in a Court of Law, then I must do so.
For those under 18, there are additional rules about confidentiality to conform to the safeguards of UK Child Protection laws.
We will talk in more detail about confidentiality at our initial assessment session, and confidentiality is a key part of our contract.
