For the tweet "@groovydadad @MHChat 🙂ty I often conflate the two depression + sadness, but they are very different. This q reminded me of that #mhchat", classify the emotional tone using the following list: anger, anticipation, disgust, fear, joy, love, optimism, pessimism, sadness, surprise, trust. If no emotion is discernible, state "neutral or no emotion".
sadness
