Be up in arms.
Be very angry.
Struggle unnecessarily.
Know everything.
Shoot oneself in the foot.
An old head on young shoulders.
Get cold feet.
Behave too seriously.
Bang your head against a brick wall.
Ruin something
Want to travel or do something different.
Give up your plans.
Have itchy feet.
Keep a stiff upper lip
Be unrealistic.
Have eyes in the back of your head.
Have one's head in the clouds.
Not to show emotions
