As someone who has had a method for years now, it brings a sense of security and feeling as if there are options (albeit painful) if I truly can't take things anymore and hit my limit. Some people say their urges actually wane when they have access to a method, due to feeling more in control and having agency over one's existence. With such a stable shelf life, it will last for years and can be put on the back burner as a means of self-assuaging. Just because another option or door options, doesn't mean one should feel rushed to make a decision, there are so many years to ponder the matter as an individual and come to whatever decision you feel is best for yourself.
Ctb is the final decision anyone can make and I think it should always be contemplated carefully and examined from every angle. There is no shame in taking one's time to examine what you want out of life and if the things that would make you happy are possible before resorting to a very final decision. I don't mean to sound like those positivity guru type people, but ctb is the last choice anyone can ever make, and there's no turning back past a certain point. That's a sombering thought demanding reflection, I know.
Death will always be waiting, but life may not be guaranteed for another day, so perhaps that elicits the strength to carry on a bit longer and have ample time to contemplate what you want. Knowing this can be comforting, that there's no rush.
