Some replies are pithy, witty, and sarcastic, and one is even “meh.” But, what they get at is the underlying fact that answering “good,” “fine,” etc., is not the only way to answer the question. We can be honest with ourselves and each other. We can admit that right now, things are far from great. We can all be a little more human and recognize the struggle of being alive sometimes.
It won’t hurt us to be more up-front and honest with each other. That’s how you eliminate stigma.
Overall though, this is more evidence of how much our mental health suffers when we do not feel part of a community. We all can play a role in making sure our community is embracing people who need that social connection.
