Is it true that God rewards our faithfullness through trials?

I have been going through this situation that I know God has been put me in. It all started a year ago. Its pretty much been a downword spiral for me. Ive been through rejections, betrayals, expectations not being met, etc. It has also brought me sadness and depression. I have yet to experience true happiness in this situation. But thru all this, God has given me strength to continue on. I know He's told me to wait, and not give up yet, but I dont know how much I have left inside to continue. All I'm wating is for He's blessing at the end of all this. But will it come??
