Bro just check my stats lmao
Dont you hate it when you lose 200 elo after people keep distracting you and then you blunder someth

If it's your opponent report them. If it's family or friends ban them from where you play at. Elo isn't always easy to get back.

practice thinking and calculating faster so that distractions have less of an impact. You can't control what other people do, but you can control what you do.
This has happened to me so many times
