Ich bin überglücklich, aber gleichzeitig nervös.

Pronunciation: Ikh bin ÜH-ber-glük-likh, AH-ber GLY-khtsay-tikh NER-vös.

Meaning: I am overjoyed, but at the same time nervous.

This phrase perfectly captures the complexity of mixed emotions—a common experience when facing exciting but uncertain situations, like starting a new job or going on a first date, which Germans often express with nuanced emotional vocabulary.
