My outside T is completely understanding. Never degrades me. Usually understands why. Just considers it a poor coping skill. I go to a PHP, where it is taken quite differently sometimes. I have never showed my SI until I was hospitalized once and it was found. I'm supposed to admit self-harm, I notified them that from now on, I will admit if I felt like self-harm and the coping strategies I have used to avoid it. But as long as the threat of a hospital was looming over my head if I went to them because of an impulse they felt was not going to be controlled or decided that my SI was too much a suicidal gesture, then I would not tell them.

So in other words, I guess what I'm saying is make sure you have a therp who understands the SI instead of one who has old or ridiculous beliefs as to the cause.
