Hi Jeff,
Trisha gave you an excellent beautiful advice, I gave her 2 thumbs up. The reason why we worry a lot is that we don't really trust God to help us in all our problems and daily concerns. If you put your trust in God and always think that He is there to do things to make your load a lot lighter, then you will have that peace of mind. You are in an age of a lot of emotional turmoil, trying to act mature when a major part of your being is very immature. This is an age of ambivalence. Everyone of us has passed that stage. So the real answer to your question is to put everything in God's hands. He loves you so much and just think that He will always be there for you if you just pause and talk to Him about everything that bothers you.
So many things bother me at times and I just have to tell myself that God is there for me, for everyone who calls on Him.
I hope that you will find peace of mind. As I finish answering this question, I ask God to bless you and help you in everything that bothers you, to make your life easier, and for you to have a better relationship with your father. I know your father loves you very much just like any parent.
God Bless you Jeff.
