Dude you're fine, i've done it plenty of time when me and the ex wife were fighting. The shaking that you're getting on startups...is something totally different. Putting the car in reverse while rolling foward would not make your car shake on startups.
You probably heard your gear teeth or something grinding when you put it in reverse but nothing else should have happened.
Don't do this again. It could be the last time you shift in any gear with that transmission.
