Your mistake was letting others know, not the money.
It only makes you unhappy if it changes your relationships. Most of it is envy from others. One of the most destructive sins that looks to tear you down. It’s based in anger. Do some damage control now as much as possible.
1. Refuse to talk about money or what you do with people you know or anybody who knows who you are (word spreads like wildfire). Find other subjects to talk about when people ask. Fun stuff, like cooking or rowing.
Little by little the people around you will either distance themselves from you, or stick around. You don’t even need to do much, just refuse to discuss it. Don’t lie (I got the watch as a gift, etc) or make excuses, that leads to other problems.
