Debating my inner voice-of-doubt

This afternoon I'm leaving to head up to the Michigan State AAU Qualifier Tournament in taekwondo. I'll be competing, coaching, and most likely judging. I'm trying to convince myself I don't have any reason to be nervous. It's a tough sell, though:

I'm going to have to spar, and I haven't won a match in competition in a while.
But you've been training much harder this year; you almost never feel like throwing up during Tournament Team workouts any more.
Still, I'm older and slower than a lot of the competitors; last year they made me spar a master (4th-degree) and she was probably ten years younger.
You're faster this year; you've dropped 15 pounds, so you go, girl!
Well, two years ago they combined weight classes and I ended up sparring someone forty pounds heavier, so I might have more of a mismatch this year.
No use worrying about your opponent, just do your best. What about forms competition?
I haven't exactly been spectacular at States the past two years.
You're doing a different form this time! Two golds in the last two tournaments!
I suppose I do look kinda cool doing that form.* I just have to control my breathing and focus.
That's the spirit! It'll be over before you know it.
But then I have to coach. What if I screw that up? Then it's not my performance at stake, it's someone else's.
You know what you're doing, you've been practicing for months, you know your teammates. You'll be fine.
I hope so. I still think I'm crazy, though.
You're challenging yourself! Eye of the Tiger and all that! Keep moving or die!
Um. Now I think I'm definitely crazy. But it'll all be over tomorrow night, so I think I'll get over it. Maybe. Kinda. Sorta. Or at least, until Nationals start at the end of June.
