I am 100% against this and I don’t think it should be allowed. You’re young fit and healthy and you want to die?
Find a way to do it. It sucks, and it’s not that I disagree that some people might be better off - it’s that the system that would allow for this would be politically untenable and likely abused.
But it’s also because not allowing people to commit suicide easily can help making the symptoms go away naturally as circumstances change.
