I think that's the most common approach. I tend to fluctuate between that and wishing to talk about my plans with others without specifying when exactly it could happen. Part of me wishes for me to not be alone in that moment but on the other hand I can't see myself being able to go through with it if I wasn't completely alone because then I'd just want to stay a little while longer. Maybe this is a weird to say but suicide feels incredibly intimate to me, doing it completely alone without anyone knowing about it feels just right in away.
Simple answer would just be yeah, I feel like that too lmao
