Cost an arm and a leg
To be overwhelmed with a large amount of work, so much so that it is difficult to handle so you feel buried
Snowed under

Get cold feet
Not what one likes or is interested in, or basically when something is not your problem
Not my cup of tea
Have a tantrum or overreact in a childish way to a situation
Spit the dummy
When you refuse to pick a side because… meh.
So you remain neutral
Sit on the fence
To make more effort than is expected of you
Go the extra mile

Let the cat out of the bag/box
It is time for someone to deal with a problem or make a decision, because other people have already done as much as they can
The ball is in your court
An apparent misfortune that eventually has good results
A blessing in disguise
To be exactly right about something
Hit the nail on the head
