What's keeping me awake..

So, I've been feeling empty for some time now.. I don't know where or to whom I can vent these thoughts to. Nothing seems to be going the way it's supposed to be. I can't find any reason to be motivated. Sure, my family's always there. But aside from them, I can't find anything worth living for. It kinda makes me feel guilty thinking about things like this. That's the problem with me, I always think. I JUST THINK. I don't really do much or do anything at all about these thoughts. I cannot act upon it because I don't really know what should be done or how and when to start.

 I can't remember when it all started. Or what caused this, really. I don't even know what the problem is. I just feel it. The emptiness. It's like, I can never be satisfied with whatever's been given to me. There's always something missing. I just don't know exactly what it is. I'm slowly losing hope. Hope that I can someday redeem myself. On how can I make up for the things I've done and should've done. How will I ever be truly happy in this life. Seems like I will never know..
