Mish: why does life is so hard on us?

I've been asking myself why do we have to go through this kind of trials? The only answer I get was maybe God wanted us to be strong and He is preparing us to a more tougher trials we will be facing in the future. I'm still optimistic and confident that everything will be okay. I'm just afraid that time is running so fast and we already wasted so much time. There's so many things we need to catch up on each other and I hate that those years changed my husband a lot more on the negative way. If only I could turn back the time. But maybe it's God's will. I entrust our lives to you, God. Whatever is your will, we'll follow.
