Look at it this way:
life sucks sometimes, but it beats the heck out of the other choice.

just wait. Something bad will happen, some crisis, and you will re-gain your zest.
I'm not wishing anything bad on you but sometimes that's what it takes. whatever doesn't kill us ..........

Maybe you can try to imagine what it would be like if everything went to crap. Spend a day or two completely by yourself away from friends and family, then imagine if you lost them all forever.
if that doesn't help make you appreciate what you have I don't know.
