I couldn't presume to know about your cause, but for me, I've found when I am not in a depressive state but am having recurring Suicidal ideation without intent that it is a function of my obsessive compulsive thoughts, not really depression. My Psychologist's office says that medication and therapy should help curb that constant ideation quite a bit. I get the concern about acting compulsively i have the same concern. I've found I often can have reasonable success in redirecting those thoughts, but sometimes it does become ridiculous how constant they are. I hope you are able to find a way to reduce those intrusive thoughts. ++
