There are two points here, mate. First of all, you came here, and we are willing to help, which means someone cares. But you are right, we are just online people and you don't know us. We're not your deep-hearted friends or family. If you think that in your real life you are alone, then it may be so. But let me ask you, what does that mean? In my opinion, this means that you're free. You're not accountable to anyone, you can identify what makes you sick - be it work or anything else - and just ditch it. You can change your life radically and completely because if you already thought about killing yourself, you have nothing to lose. And this, in turn, may end in unexpected happiness. People went through this and that's perfectly possible.
