YOU should not feel embarrassed or guilty. The car driver, on the other hand, is clearly at fault. You do NOT, EVER, back up a car without checking carefully what's behind you and what's coming past from either side. That's the law! Any time you hit something while backing, it is your fault. Leastways, that's what I learned in driver's ed all those many years ago. So the driver should be the one feeling guilty and embarrassed. Luckily, you can both also be feeling relieved it didn't turn out worse.
