what is life for? epiphanies at 1 a.m.

I am always, always wondering ... like we probably all are... why it is that

a) I believe in God (i.e. is it real belief or is it fabricated through social conditioning? is it me and my emotions, which sometimes create these physical encounters I interpret as a small sign of God saying something like: "hey, it's me. just in case you were wondering where I've been."?

b) if God exists, why is it that so much bad happens in this world and how do people manage to stay faithful to God in situations far worse than we could ever imagine (e.g. civilians in warzones, people struck by terrible fates, illnesses, etc.) ?

To the latter question I come up with plausible explanations once in a while. Not always do I write them down but tonight's thought struck me rather hard and I just had to write it down to get it out of my system.
What if we are just not meant to be happy and blissful in this life? What if that is just an added little bonus given to us in a special way... unconnected to all material values in this world and thus attainable for us all (if we just figure out how). Everyone knows the saying "happiness comes from within" .....
So, what if life is really not meant to be all that great?
This is, of course, a rather depressing thought and maybe I've just spent too much time in the city.

Today, on my way home, I suddenly found myself in the middle of a police-car chase (gunfire in the distance and all), watched an undercover cop put his knee into some guy's neck to handcuff him, and then was forced to back up an entire street (against the one-way direction), almost losing my mirror to one of the police-cars racing by me.
As I was walking the dog later, a bit depressed about the human darkness (yeah, watching Harry Potter tonight didn't help either), I thought hmm, and this isn't even that bad. What about the people in Afghanistan, in Sudan, in Iraq, wherever, ... that's where it really sucks...and what do you do then? When you're trapped in a situation like that? Your children, your family dying around you? People killing each other on a daily basis? How do you find God then? ............ God, ...it really must suck being God. ....... it's hard to keep everyone happy.... So, that's when the thought sprang to mind that this might not be the objective.
Maybe we are here to learn. Learn to help each other. .... But, somehow I'm not seeing that this plan is working....so maybe that isn't the plan. ....ugh...humans suck. ...most of them, anyway.
So, can't you tell me how I could help [in this world] more efficiently? ...I mean, that can't be it, can it? A couple of donations here and there....trying to be a good person..... that can't be all? That's a mighty measly contribution I am making here. Is this all I am here for? Come on, use me.
I am willing to make sacrifices.
And then I thought about the graveness of my easy talk. How much am I really willing to sacrifice? How self-less am I really? Donating money & time is easy.... ..... I am just another human.....
