I have come across the following as examples of "orientational metaphors":
happy is up; sad is down:
I'm feeling up today. He's really low these days.
While I understand the general concept, I do wonder if native speakers of English commonly use "I'm feeling up today" in daily conversations to express their (temporary) sense of well-being.

Typically you don't hear 'up' used in general conversation. The use of 'down' to indicate sadness or depression is quite a lot more common.
'High' is in occasional use but it generally refers to artificially imposed moods.
