My blood is boiling
I am under the weather
A couch potato
It’s raining cats and dogs
Cost an arm and a leg
A piece of cake
In hot water
Hit the sack
Butterflies in my stomach
Something that you say when it is raining heavily
Go to sleep!
Very expensive
I am sick!
Nervous and anxious
Very easy!
I am very angry!
A person who doesn’t have an active life
To be in difficulties
