I'm bipolar and I don't technically SI. I just get so mad or frustrated that it's me or the person I'm mad at so I try to knock myself out. I realize it's a bit different but I gave myself a concussion. When I went to the hospital I explained what happened. That I had a blowup. I'm mentally ill there are going to be hiccups in treatment. I'm fine now ask me whatever you want. They asked me a few questions told me I really REALLY need to be back on my medication and sent me on my way.

I can not guarantee that you will have the same experience but I have found honesty and not getting overly agitated or emotional has been the key to me staying out of the hospital.
