What method did you use?
Everyone's problem here is uncertainty, the lack of knowledge of what will happen after the action that leads us to the final moment. No matter how much we have read or seen about our method, there will always remain a doubt, no matter how small, about what will happen now?
I plan to jump, it's nothing, 2-3 seconds of falling, and even so, my brain boils with ideas and possibilities.
It is awful. If you really want to do it, with an iron mind you will achieve it. You don't have to apologize for anything, not even to repent. After my first attempt I lost my right leg and to this day there are still people who ask me if I regret what I did. I answer no, that to a certain extent I feel proud because not too many people would be capable of doing what we suicides do, we are cowards in the eyes of the philosophy of life, but truly brave in the field of decisions.
