Although today is sunny, my emotion is’t good.Because tomorrow willod isn't doing well because term begins tomorrow！！！😢 Although today is sunny, my mood isn't doing well because term begins tomorrow！！！😢

"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！！！😢"

Although today is sunny, my emotion is’t good.Because tomorrow willI'm not doing well because term begins tomorrow！！！😢 Although today is sunny, I'm not doing well because term begins tomorrow！！！😢

Instead of "my emotion isn't good," use something like "I'm not doing well" or "I'm in a bad mood."

Although today is sunny, my emotion is’t good.BI'm not happy, because tomorrow will, the term begins！！！😢! Although today is sunny, I'm not happy, because tomorrow, the term begins!
