<human>: Could you distill the essence of the text into 1-3 sentences?

Not sure where to start. I used to play lots of sports and wasn't very competitive but lately I've noticed that I've become a sore loser and get frustrated easily when I'm losing anything or not doing well.

Example 1: Today I played racquetball for the first time. I had gone to a tennis camp or two when I was young so I didn't think I would be horrible but I was the worst of the 4. I was frustrated because I was making my team lose, no matter who my partner was, and they had to do rock paper scissors to see who would get "stuck" with me as their teammate (the other 3 had been playing for awhile together). I was clearly frustrated and my boyfriend, who was playing with us, asked me repeatedly if I had fun because I didn't look happy. I enjoyed playing but feeling like the last kid being picked for dodge ball doesn't make anyone happy, it made me feel like a burden.

Criticism relates to this because I get frustrated when I'm being offered criticism, particularly when it's a game.

Example 2: I was playing a new card game with my boyfriend and 2 of our other friends. I was on a team with my boyfriend and 1 of the other 2 players hadn't played the game before. We were playing but I messed something up and they laughed at me for doing it and then proceeded to tell me all of the other ways I could have played my hand better than I did. I know I was new to the game and I didn't expect to win.

I could give more examples but you get the idea. It isn't even really losing, I don't mind if I'm last but I hate being so far behind everyone else in skill that I look like an idiot and then I'm critiqued like an idiot. I'm trying to be mindful of all of this but I still just get frustrated and take criticism as personal attacks and feel hurt.
<bot>: I've become a very sore loser and become hurt when I am critiqued. I want to change and become more positive but I don't even know where to start
