Wondering

Will bad always out way good in this life?
I know there will be bad, and lots of it... But will there ever be more good than bad? I don't know if it's just me having a bad perspective or not but even when I have an idea as to my future to some extent, and a few good things coming, I'm still not happy. I just don't see the joy in life (except for "the joy found in Christ"... Which I think just barely keeps me above depression).
Is there something I should be doing differently? Something I shouldn't be doing? I feel like I'm whining and depressed and stuff all the time... Even when I try Really really hard to be positive and see the joy and whatnot... I always fall back down to the bad. Where is the joy? Even though I know it's ok to be broken and ok to be in pain and ok to show pain... I still don't ever show it. I can't. I don't think this is a question I'll have answered until I get through life either... Waiting that long to have a question answered really sucks! But, as always, I'll grin and bear it.
