I've been working on trying to maintain my frame and confidence in different situations like rejections, interviews etc.

One thing that I somewhat struggled with lately was losing a game against an opponent. Usually, I just brush it off since its just a game but that opponent was a bit provocative. He mocked my every mistake but I played along (I enjoy a little bit of verbal banter in sports) but then as it continued, the mocking kept on going. I was also losing lot of matches and I lost my frame a bit.

What would be the best way to deal with this? Continue playing and losing the match while being mocked. Enjoy the verbal banter and keep your frame OR

Once you lose a lot of matches, exit the game?

Also, let me know if I'm overthinking all this which might be causing me to lose my confidence and frame.
