That sinking feeling

Well, shit. Had a session with the personal trainer today that started out strong (measurements and weight down, gained an inch on the sit-n-reach, held steady on number of pushups and situps in a minute) and did three minutes of step-up exercises without really wearing myself out too badly. Then he had me do a sort of feet together hopping thing, up onto the low platform (just an inch or so off the ground) and off the other side, back and forth, for a minute. Reader, I crashed. Finished the exercise successfully, then promptly spun into a hyperventilation fit where I had to sit on the floor and try and control my breathing because I was panting, my vision tunneled, and I wanted very badly to barf. Recovered from it, did a couple of machines, and managed some squats before the sparkling in front of the eyes started to creep back in and I called it a day. Checked my blood sugar, just in case, and it was right where it should be.

Trainer thinks it's hangover from the walking pneumonia and also that I need to work on good breath control, so he's told me to start walking slowly on the treadmill at a slight incline, focusing specifically on my breathing. Meanwhile, I am trying not to be discouraged.

Blah. I hate feeling that way, and I hate thinking that I'm about to barf in public. I am less than pleased right now.
