Currently disillusioned by life..

Every time it seems like things are FINALLY looking up for me, I'm met with yet another disappointment. I strive on and try to continue being positive, only to have life deal me another harsh blow. People say it is our faith that gets us through these times and that it is during these times that you need to hold on, for the next great thing is just around the corner. Well, I've been doing that, holding on and praying for relief, for the past year and yet things still do not change for me. How can one not question their faith in these circumstances?
