I feel like only you can decide what method is the best for yourself. My access to methods is very limited personally, I am trapped in this world as suicide is so difficult. I plan to research my chosen method when I get extremely desperate. It frustrates me how difficult it really is to leave this world, all that I want is to pass away peacefully. The fear of failure is what holds me back. I'm sorry for all the suffering that has brought you to this point and I wish you the best in whatever you decide to do.
