Why worry?

Luke 12:25
             25 Who of you by worrying can add a single hour to your life?

  It never fails, I always get caught up in worrying about all the things I have no control over. I know at the end of the day it's all in God's hands, however, I can't keep myself from thinking the worst in every situation.

I need to pass the national test.
                  I worry I won't pass, because that's the worst that could happen.
                  If I don't pass I won't be able to get another job soon and end up being a failure.


I need to get another job.
                  Hours are being cut dramatically and I'm barely making anything.
                  It's dreadful going to work there and I'm sick of feeling worthless.


I need to figure out what I'm doing with my life.
                  All of the unknown aspects are driving me insane.


I want the doctors to figure out what's wrong with my daddy.
                  ... And this one is the one that matters. This is the one I have absolutely no control over.
                  I want my dad to be happy. I want my dad to be healthy. I want my dad to live forever.
                  Isn't that what all children want of their parents? Is it asking to much?

I know there's kids out there, everyday, who don't have what I have. I know I'm blessed more than I'll ever know. I should have nothing to complain about.

Father, whatever happens to me, and my life, whether it's failing out of school, not finding another job, or never figuring out what my life's purpose is, just keep my father healthy. He deserves the best life. Please comfort him, while he's in pain. Encourage him, when he's in doubt. Heal him, if he's sick. 
Thank you Father, for all the blessings you've placed in my life.
