Having common sense is the best way to achieve what you want.
Life is not something you can just turn off with a button.
Closing the circle of life requires some effort on your part. And searching for the magic key is a waste of time.
We don't live in a fairy tale where you can make everything come true.
We live in the real world, a world filled with all kinds of problems.
Carefully considering the methods that people and I have offered you will help you determine which one is right.
I've noticed your ADHD a lot in you, and yet, you've made me doubt if I was misdiagnosed, because like you, I also have ADHD, although in my case, I'm inattentive.
I'm sure ADHD makes you feel indecisive.
If you've been hyper-focused on the methods, you should think on your own about the right option, based on lethality, pain, budget, and impact. However, you've been conflicted about these four mentioned aspects.
For the most effective methods, you need to invest money, but you don't like being in a capitalist place.
For the most painful methods, you need willpower, but you don't want your death to be painful, and you also don't want it to be bloody. However, later, you change your mind and don't mind if it's bloody.
You don't want to die, but you want to fall into a coma, and never wake up. Inducing a coma by disrupting your vital functions is like waiting for a lightning strike to give you a cold.
Things don't work that way. Thinking about all this will only waste your time.
You have the right to choose any method you wish. But this is a forum to help people escape from this world, not to enter into middle ground.
In summary, the problem isn't the methods; it's that you're indecisive, and this is due to your ADHD.
