Hummmm i don't think either that English people would say "how is your morale", if asked that, i would think that the person is referring to my values or ethics. i “googled” “how is your morale” and got only one hit : http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1828239/ to ask "comment va le moral" i'd say : -how have you been feeling lately ? -how are you doing ? -are you alright ? -everything's fine ? and, strangely i feel like the answers are closer to your idea of "moral". -i'm in high/low spirits -i feel elated, great or on the contrary … I feel down, dejected, despondent -i'm in/out of shape = je suis en grande/petite forme (though I think it mainly refers to your physical condition)
hope it helped !
note: if i'm wrong somewhere, please, do correct me. thanks !
