The decision to commit suicide can happen within 5 minutes. As Rush says, don’t doubt me, lol.
I have had to deal with a lot of suicides in my personal life, and I do disagree with you, suicide is not a 5 minute decision, the internal conversation and takes place over time.
I wonder if you are confusing the act itself with the decision process and the long road to even weighing whether suicide is an option, to it becoming the only option, to the execution of the decision.
