It has been my experience that most ppl do have SI and the thoughts come and go. I believe it is typically brief and momentary. I know for myself those thoughts come when very depressed. I don't like to think about them because I have had past moments that I acted in them. Not a good thing and I know I have hurt the ppl around me. Unfortunately I have two siblings with different dx and I know the one has bp as well and he has SI. Not sure this is what you were looking for. Take care of your self
