I am not/was never "competitive," however, I am/was a perfectionist. I have a hard time forgiving myself for my flaws.
I had the "sore loser" issue and it was triggered by the following:
1. Control issues. I lost a game, my "control" was lost. Not cool. Games, much like social interactions with other people, are random, unpredictable, and aggravating.
2. Poor motor skills, especially in front of others. It's extremely frustrating when your body won't do what you want it to, especially when you're being yelled at or made fun of. Ditto that for any other skills such as following directions, keeping track of score, ect. that your particular Aspie may struggle with.
3. Sensory overload. Self-explanatory.
4. See above. Perfectionism.
5. Winning feels good. Normal kids got to win at stuff. Unfortunately, most of my interests didn't lend themselves to "competition," at least not in the dramatic sense where you "win" to the sound of applause and peer acceptance.
6. Extreme/rigid thinking. "I suck at this. I suck at EVERYTHING!! !" *Initiate shutdown/meltdown*
That's about it in a nutshell.
