Well, we all have some kind of reason. I don't know why would anyone want to help you, but remember that everyone has their own reasons.
I have my goal in life and I am doing it. If I'll see that there is no point in that, I'll just think of something else or just quit and enjoy life. I don't see the point in being sad or in the Dark night :D
You might have misunderstood me. One does not choose to be in the Dark Night. You arrive there after experiencing a major disillusion about yourself and the world. If you don't understand it and would not want to experience it, good for you! Just keep going...
I'm sorry, I must sound very confusing. It is not an easy topic to talk about. I just hope that if it happens to you one day, you will remember to type "dark night of the soul" in google and let someone more articulate explain it : )
