How to take losses without quitting mid match or giving up mentally mid match

I’m trying to get better at dealing with losses in UFC 6, especially when I’m fighting someone who is clearly better than me or is simply playing much better that match.
It gets tiring how hard it is to outstrike my opponent, once I realize the match isn’t going my way (Like 7 times out of 10), I start giving up mentally or feel like quitting the match entirely. How do you guys deal with these situations? How do you stay focused and keep trying to win, even when you’re getting outplayed and the match feels almost impossible? I also tried to harden my self up staying in the match where im losing and i noticed that it makes the next fight easier because i fought a better opponent
