Alright I'll state my point of view.
Honestly, I think near 3/4 of the post were redundant, stupid as well? I somehow could predicted cloud's purpose in asking this question relates to some suicide thing. Questions were never meant to be stupid, everyone has different level of thinking. If you think you're so smart, post your own thoughts on this and we see how smart you are? I'm not targetting this on anyone but what's so smart in asking, "What handphone to buy, What girls to catch, What celebrity do people say you look like?" If you're telling me this kind of questions are less stupid than, "What is life all about?", think again.
Cloud: I'm gonna summarise my thoughts into one paragraph, and I hope it helps.
Basically, you're borned into this world for some purpose. I'm not a religion person, free thinker is the term? But I believe that each of us live for a reason. If you die, you typically screw up the system. You may feel lost now, as you don't have dream, targets or goals. Hence, many think, what's the point of living when we're all waiting for death? What I can suggest to you is that, do something you've never done before, try and explore. For instance, go overseas enjoy, go watch R21 movie with a gay, etc etc. I'm just giving you an example. IMO, Singapore is a boring place, but it is up to the individual on how they wanna spice up their lifes. There's just so much things in life you can do, sometimes I feel that I'll never live long enough to finish them all. Cherish your life and your family, your friends and all. No one will want anyone die just because they gave up on life.
Alternatively, I suggest you call those hotlines which can help you. You really need some proper help/guidance on this. And hey, I'm not a professional

Cheers!
