just relax and stay on your feet, really
I know that sparring isn't the simplest thing to do, but it's not all that hard (which sort of makes it unexciting sometimes)
practice launches and landing on your feet, then onward to twist, then onward to damn near tricking.
your legs and knees do a good portion of your momentum control, as well as your lumbar/chest
when you're in a bad position, relax most of your joints and move very few of them to get back on your feet/in proper position
keep taking your time, and you'll be fine
