I'm worried about my dad dying?

I think its really nice that you and your dad are close . Anyways we all worry about our parents dying that's just a part of life , you should not worry it will only make you sick . I think maybe you should talk with Your dad and tell him whats going on and how you feel when he goes to work or maybe your preacher at church..So relax talk to dad and let him know . I think you will feel better...GOOD LUCK......................
