I don’t care and you could do as the same.

People always talk. They talk about everything either related to their lives or not. Generally, they talk about things way out of their leagues more than their real issues. So as they talk so much about you or many people talk about your issues, it means you are surrounded by people those are way out of your leagues. Don’t try to convince them. Don’t waste your time on overthinking of their meaningless crap! Change your people! Surround yourself with people that encourage you and inspire you.
