Feeling: Is It A Blessing In Disguise?

I felt stuck with every problems that I face lately.
I am running out of energy, I feel sick. Why trials of life seems never end?

When I tell a friend about this, he suggested me to listen to this song which I found really suited to my situation. Laura Story - Blessings...

As I quote the lyric:

'Cause what if your blessings come through rain drops
What if Your healing comes through tears
What if a thousand sleepless nights are what it takes to know You're near
What if trials of this life are Your mercies in disguise

But my question remain: Is it really a blessing in disguise?
I can't see the Lord's plan for me. I know He has a wonderful plan.
Grant me the strength I need, Lord, so I can face this.
