It was explained to me in the hospital that having the thoughts but not the urge to act on them is passive suicidal ideation. Having the urges to act/having a concrete plan is active suicidal ideation and requires immediate attention. From what I'm understanding your having passive thoughts. This could go either way. Personally I would seek the help of my therapist in this matter, or even my pdoc because it may be a medication reaction if youre on any meds. And if your still having the thoughts severely and often I would contact the crisis team in your area, they'd be better equipped to help you right away. Best wishes!
