Losing Faith??

So, when we are beset by calamaties, some big some small but all of them at the same time, what do we do? Sit, suffer, sulk? Why do these things happen at the same time? Is it to compensate for the previous happiness and goodness that we are accustomed to? Or maybe the prior is just placidity marked by little or no unhappiness. Maybe the bad things suffice  to keep us in check and to appreciate the things we should truly cherish. I know which things are that truly matter but a few things in the right direction and some guidance would be greatly appreciated now.   I personally have a faith in the Christian God and that no matter what happens to me it is all for a ''grand design'' or some greater end purpose to which I can not see at the moment. It is hard for me to not be curious as to exactly what that is when I feel as if I am being hammered into the ground like some confused, perturbed nail. I will never give up my Christian beliefs in the eye of hardship, but I tell you what.......it sure isn't very easy to keep my focus.
