Student or Learner
Here are some expressions use to descibe happiness. I posted them bacause i think they may be of use to some learners in this forum.
To be floating/walking on air
To (be/feel) over the moon
To look full of the springs of life
To be walking on air
To feel on top of the world
To be thrilled to bits
If an event makes you very happy we say ""it sent me into raptures.
It will be nice if teachers or natives may add any other common expressions. Informal expressions are equally welcome as well.
To be full of the joys of Spring
Oh, yes it is "to be full of the joys of spring"
I'm tickled pink
I'm as happy as Larry
