I do not think anyone here will wish you luck in succeeding whatever it is that you are considering to do that may or may not end your life. It is not just forum policy, but also because they care about you.
Consider this: How do you know your method is truly "painless"? How do you know your method will succeed? You don't. What if it fails and you end up in a worse situation in the end?
It is always better to let others know what is bothering you rather then keeping it inside (I'm still trying to get used to this myself...). So, rather then risking the slim possibility of ending your life (and ending in a possible worse situation), why not talk to the forum members about your situation? Who knows; many members here might have very valuable advice for you
