If even a part of you says no, then the answer is no.
I personally would never adhere to this mindset, because if you look at suicidal people, they're
almost always ambivalent, so
if I use that mindset,
I'll never achieve success in CTB.
ambivalence can mean:
1) "The simultaneous existence within a person of both positive and negative feelings toward another person or action, or toward an object (as of attraction and revulsion), resulting in internal conflict."
2) "The coexistence of opposing attitudes or feelings, such as love and hate, toward a person, object, or idea."
3) "Uncertainty or indecisiveness as to which course to follow."
etc…
self-extermination is
one of the most anti-natural things we can do as biological organisms, because we're
programmed to survive, reproduce and help the off-spring's chances of survival and reproduction,
so having ambivalence in suicidality is naturally the norm.
therefore I think this type of mindset can make me
stuck on Earth for decades - even if I'm
deeply unhappy.
although obviously, this is just my personal opinion and I know that the same subject can be viewed from multiple points of view, depending on a lot of individual circuntances.
with that said, you're right when you say that CTB is not the only option. it definitely isn't. sometimes we haven't found yet the solutions to our problems, but it doesn't mean they don't exist. a lot of things can be done, always (although I don't really want to do them).
