Mine are
1. I don't see any possible reason to believe that the future will be any better than the present with the way circumstances are unfolding, I don't see any reason to be convinced I'll be any happier sticking around and hoping that things get better when by all accounts, life gets harder as you age which is not something I'm not looking forward to in any sense no matter whether or not, I have some support.
2. I don't see any reason to continue the struggle of existence any further.
3. Death may be unknown but I don't fear it as nearly as much as staying alive for another 30-50 years with more climate change, wars, corruption, greed and inequality and also just dealing with the consequences of selfish actions by human beings that cause indefinite harm.
4. For years, I've sought methods from full and partial hanging to Potassium and Sodium Cyanide ingestion, Severing the carotid artery with a Knife, a gun, ingestion of sulphuric acid and even inert gas, some were not obtainable due to restrictions, inconclusive research and cost so SN had appealed to me because it is obtainable and because quite a few users on this forum have completed CTB with it so this will be my route.
5. I can't bare to see how could I go on with my suicidal ideation never ever far away in my deepest thoughts, I know I don't want to be here any longer than I need to.
