Happiness + bewilderment =?

I am looking for a word that combines happiness and bewilderment.

Say, A and B are long forgotten friends. After a long time B sends A very very good news. A is looking for a short message, a word that expresses his happiness and bewilderment in response to the news.

What would be the word combining these two — happiness and bewilderment?

Solution 1:

It's not one word, but the common expression pleasantly surprised comes to mind.

You might also consider astonished, although I think that connotes amazement rather than happiness. It's still a positive word, though. Thrilled is probably even better.

Solution 2:

Friend A could reply, "I am....:

Flabbergasted — overcome with astonishment; amazed; astounded

Thunderstruck — affected with sudden astonishment or amazement

Gobsmacked — utterly astounded (British slang)

Floored — stunned; overwhelmed: The very idea floored me.

I think gobsmacked, even though I am in the U.S., is my favorite.

Solution 3:

Agog might fit the bill. Thesaurus.com shows it as a synonym for bewildered, ardent, eager, enthusiastic and breathless.

It’s used in the manner you seek in several examples. In From This Far Distant Shore, Richard Curtin wrote “Transfixed by a prism of changing colors he gawks at the hypnotic pulse of alternating light. Agog in pleasant bewilderment he follows the image waltzing to the tingling crystal spheres.” In Promises I Made My Mother, Sam Haskell wrote “My father stood there agog, not quite believing his eyes, but happy for me.” I will admit that the term can also sometimes be used in the same way as amazed – unpleasantly shocked – but Common Phrases: And Where They Come From likens “all agog” to “Somebody eager, perhaps even ‘starry-eyed’ over a happy event.” The term seems variously used as simply “agog” or amplified as “all agog.”
