I've thought about how I should respond to this, and I don't want to make the typical 'your life is precious' response. I'm not saying that your life isn't precious, but maybe that's not what you want to hear right now. I'll say that I've been where you are right now, and I've experienced suffering. Sometimes I've wondered whether or not my life is worth living (that's an understatement).

What I want to say is that what helped me bring meaning and purpose to my life is gradual but relentless self improvement. When I've successfully changed or improved upon some negative aspect of my life – I feel really, really proud. It doesn't matter how seemingly small the change was, or how much I struggled in the process. I don't care how long it took me, the simple fact that I didn't give up is enough. Knowing that I managed to improve my life or myself in some way is my favourite feeling in the world.

I hope that this helps... but if it doesn't, at least it gave you a momentary distraction!
