Nope, I don't.
DH is a huge worrier. If we're tight on money, or the computer doesn't work, or even if the button on the microwave sticks...he loses it. He gets stressed over incredibly minimal things. He's on medication to deal with it.
I tend not to stress at all. I guess I just think, what will worrying get me? Will it solve the problem? If not, I don't give it a second thought.
