Deadliest catch makes me cry

I was sitting here watching deadliest catch and one of the captains had a stroke. All I could think of when they showed him lying in the hospital bed was seeing my dad is a similar position. It was the scarest thing that ever happen and for weeks after my dad had his all I could see when I closed my eyes was my dads face. I still have nightmares about it even a year and half later. I'm so happy that my dad has completely recovered but it still scares me that he might have another one.
