Having an open house after finishing a renovation is showing off, Anna, but there’s no reason to be ashamed of it. Your friends and neighbors are dying to see what you’ve done with the place! I’m sorry you’re struggling with anxiety over your financial well-being.
It’s ironic because most people think having what you have would put an end to their anxiety. Just be grateful, generous, respectful, and kind. The only time people think badly of people with money is if they’re jerks. Life is too short to worry over what people may think. Enjoy your life. It sounds like a good one.
