I see by your profile you are in New York. if thats the NY state in America yes, this state has mandated reporting laws that say treatment providers must report when their clients are a danger to their self and others by way of suicide /self injury or homicidal. (this law has been in effect for a long time though it is strictly followed more so now because of 9/11 and NY's zero tolerance for violence to self and others laws)

that said most treatment providers also understand that sometimes self injury can be managed out patient ....if.....the client is willing to be honest, forthright and actively work on the problem.

example me...I sometimes fall into self injury. the first few times I did so while under the care of a mental health treatment provider I was hospitalized for being a danger to myself and possibly others.

finally on intake to a new therapist I told the therapist first thing. she asked if theres anything I wanted her to know about me before we started getting to work. I said yes I have a history of self injury, this is what I do and why, and this is is how long its been since the last time.

that therapist thanked me for being so forthright and right then and there we drew up a treatment plan and contract that basically stated I would tell her ....before .....I self injured that its becoming a problem so that we could work on the problem that was causing the self injury thoughts ...before...they became actions that would need inpatient care according to the law.

this has worked out great for me. every treatment provider after that one I always informed them it was an issue so that we could deal with the problem out patient before it reached the point where the treatment provider had to follow the state mandated reporting laws.
