Use each of the 9 new "feelings" adjectives (cansado, nervioso, etc.) TWICE, like this:
Estoy (adjective) cuando .... (finish off in English, to tell when you feel that way)
TRANSLATE the Spanish.... Translate Estoy as "I feel"
Estoy nerviosa cuando there is a mouse hiding in my room. (= I feel nervous when...)
Estoy nerviosa cuando I have to drive in the snow. (= I feel nervous when...)
NOTICE that I ended nerviosa with an A.... because I am describing myself, and I am a female!
