This isn't like a fear, but something that happens all the time.
I'll go first, I worry about finances since DH wants to change careers so late in the game. He's not a handy person, so I take care of the house, missing roof tile, filling in holes on the side of the house (darn AZ woodpecker), bugs, car problems etc.
ETA: State a positive thing going for you - what you are grateful for!
I'm grateful for a smile every day, and a chance to share that joy with my DH.
Now you go.
