To reiterate what spunt said, this is not a sign of someone actually thinking of ending things. I also speak from experience and the sheer magnitude of what you are going to do and the place you are in means you leave no clue as to your intentions and you certainly don’t set yourself up as a supporter for other people in the meantime. You quietly close yourself off and begin making plans. My attempt was stopped purely by chance by someone spotting me at 3am swimming out but she has less options due to her weight and physical issues, so would need access to serious weapons or rope that I doubt she has. This is pure bait that anyone can spot who’s been close to it and spits in the face of people really suffering. She can fuck off.
