Stop the world, I want to get off.
This was said to someone complaining about life in general.

Put a damper on
means to discourage or depress.  On a piano a damper stops the strings sounding.

Browned off
means the same as
cheesed off and
fed up (to the back teeth).
Anyone who has had toothache, especially involving the back teeth knows how miserable it made them feel.  Fed up means having had enough.

Down in the dumps
means depressed or miserable.  A dump was an old word for a rubbish tip.  Now rubbish tips are becoming recycling centres, which must be a change for the better.

Without a care in the world
describes a person who seems very happy.  I wrote a verse recently about modern attitudes to happiness.  Click here to read it.

Fair-to-middling is defined in the Concise Oxford Dictionary as slightly above average and is sometimes given as a reply to the question, “How are you?”

Ticking along nicely…
I haven’t found a definition for this, but I imagine it is an analogy with a timepiece which is working regularly.

Tickety-boo also means all right.

Full of beans
means exuberant.  Tigger in the Winnie-the-Pooh books is a good example.

A peck on the cheek is a kiss.  Keep your pecker up
really means “keep smiling”, but has been hijacked.

Over the moon means delighted.

Tickled pink also means very pleased.

Like a cat that’s been at the cream means self-satisfied.

Like a dog with two tails refers to a dog wagging its tail in pleasure.  If it could wag two tails it could show it was twice as happy, perhaps.

Dog-tired means exhausted.

Cry your eyes out means weep until there are no tears left.

Infectious laughter
is the sort that everyone joins in with.

In the Bible there are many examples of the whole range of human emotion.  Psalm 6 is a good example.  The author, David is feeling wretched but has hope through his faith in God.
