Examine the tweet "We can replace #loss with #hope, #hate with #love, #pain with #gain, if we close the window of #bitterness and open doors of #faith. #TryIt" and determine which of these emotions are present: anger, anticipation, disgust, fear, joy, love, optimism, pessimism, sadness, surprise, trust. If there are no identifiable emotions, reply with "neutral or no emotion".
