You're not pathetic or a coward. It sounds like you're still thinking about ctb a lot, even if not planning it, so by definition you're still suicidal.
Suicidality isn't a dichotomy (i.e you either are suicidal or you're not) rather it's a spectrum. It ranges from a one off passive thought ( e.g thinking I'd be better off not being here' but never considering acting on it) to intense absolute certainty you want to die, always on your mind and succeeding in ctb. If everyone who had a suicidal thought in their life successfully acted on them, we'd have a much smaller population. Most people sit somewhere in between the 2 ends of the spectrum. And where you are doesn't necessarily correlate with likelihood of dying. For example, someone may die after a one off impulsive thought and another person may be certain they want to die but don't due to circumstances.
But wherever you are on this spectrum, your pain is valid and real. And every place on it is a shit place to be. You deserve support to live or a peaceful way out, depending on what you want.
Nothing is 'wrong' with you, you're clearly struggling with life and that's not your fault. It sounds like you both have reasons to live and reasons to die. It's okay to be unsure . CTB is a huge and (especially with something like SN) likely a permanent decision. It's natural to be unsure. Being suicidal doesn't mean you have to die. Here we believe you should be able to choose to. But equally you can choose recovery. If you're unsure, I can't tell you what to do but I would urge you to take your time to consider what you want. It's okay to take your time. You mention therapy, is that something you haven't tried before ? Some people do manage to live with their suicidal thoughts after therapy and/or medication. It doesn't help everyone and there's a lot of different types out there so can be trial/error. But might be worth a shot ? You've got nothing to lose really. Maybe read others' experiences on the recovery page here ?
I wish you all the best and peace whatever you choose. Your feelings are valid, real and incredibly difficult regardless if you choose to try recovery or choose to ctb.
