"emotional state" is how you would use "emotion" in this context. However, "emotional state" sounds dry and clunky, "mood" is the casual equivalent.

Concepts like "mood" and "health" are treated as ongoing events, so "my mood is good" sounds wrong, but "my mood is doing well" sounds correct. If you use the adjective before the concept instead, you can use "good" or "bad" and it will sound correct. For example,

"Although today is sunny, I'm in a bad mood because term begins tomorrow！！！😢"

Well,tThis isn’s a bad event, but't entirely a bad thing because I can meet my classmates, I haven’t seen them since January again.
