I am currently:
 

Is there any way you can add "Unknown" to the list of emotions?

Or possibly a synonym that would mean "I am not sure what my mood is right now because I am confused about what I feel"?

hmm the best I could find for you that is already there is "Inexplicable" or maybe you could go for something vague like "Meh"

We are already close to having something like 200 moods, so I'm not sure if we are going to be able to add any more.

Thank you.

Although "Meh" sounds too grey/slight depression,
"Inexplicible" will help me.

I should've written my thing better.
Thank you.
