I expect there aren't many of us in this forum that haven't done something just as stupid
I think I've only dropped my bike at a stand-still once and it was from a similar thing to you. In my case I wanted to check my brake light was working so I pressed in the rear brake pedal and the bike lurched forward and then dropped to the ground. Turned out I actually pushed the shifter instead in a moment of nooblidity (noob stupidity). I managed to set it down relatively gently so only got very minor damage.
Glad you're ok. Alex's advice is good! Also: Alex is the boss so you kinda
have to do what he says
I'm curious: have you driven or ridden anything with a manual gearbox before? Over here manual gearboxes are the norm on cars, but apparently in the states it's more rare and most people drive automatics.
