If you are over 18 the only people your therapist has to tell depending on your therapy agencys protocals is his/her supervisor and or refer you to the local ER because here in the USA a person who is a danger to themself and or others is basically committing a crime.

MY therapist knows that I self injure. and this therapy agencys protocal on it isthat the person must be referred to the local ER if the suicide attempt and or cutting attempt is made within the past 24 hours of seeing the therapist. Which is why I do not for the most part discuss my self injury behaviour with my therapist. She knows I do it and she knows I am working on it and how I am working on it, but I will not put her in the position of having to follow this states law and the agencys protocal for self injury/ suicidal behavior by showing her or telling her about any self injury acts with in 24 hours of seeing her. To do so would put her in a very hard position of following my wishes not to be hospitalized due to the fact that I was raped on a mental health unit or following the state law and the agencys protocal. So instead I let her know that I do self injure from time to time and that I am working on lessening how much I do it and how I am accomplishing that and both her and I leave it at that.

At your intake appointment you might have recieved a paper about the agencys privacy confidentiality protocals. Usually how they have to hande suicide and self injury are included on that paper. You can look at your paperwork and or ask her what the state law and the agwencys protocals are on such behaviours and she/ he will tell you what you need to know to decide if you want to tell the therapist or not at this time.
