I have heard two quotes from friends, in the past year, which I have held close.
Quote number 1: “It’s none of your business what someone else thinks of you.”
Quote number 2: “I don’t do negative energy, I don’t have the time for it.”
All you can be, is your personal best. Don’t doubt yourself. Like Oprah says, “Get up each morning and be the best you you can be.”
It sounds like negative energy to me, don’t waste your time worrying about it. It will gnaw at you and steal away your creativity.
