Why be nervous?

I struggle with being nervous. I get nervous about silly things as well: things I shouldn't even worry about at all. When I get really nervous it starts affecting my health. I get huge headaches, my stomach aches like no other, and my breathing gets all weird. I hate it when I get this nervous.

In the bible it says that we have nothing to be nervous about, and that God has everything under control. I believe with my whole heart that this is 100%, but I still struggle with turning all of my worries and selfish ambitions over to the Lord. I'm not really sure why I struggle with this so much. At church, I have talked to a couple of really Godly women about this and they all said that they have struggled with it too, and that you just have to give all your worries to the Lord.

So my goal is to not worry at all. When I catch myself worrying, I'll pray about it. This issue has to be fixed. How can I say that I love and serve an almighty God yet I still worry? Today in the sermon, our pastor made an excellent point. He said, "Think about how truly amazing it is that God is sovereign over all. Think about how messed up this world would be if He wasn't sovereign. Shouldn't we be thanking God everyday because He is sovereign?" He hit the head on the nail. I concur.
