Honestly I probably did that when I first started as well, but I didn't lose anything as precious as a shiny Wurmple :( I think my most facepalm-worthy moment was when I used a master ball on an Absol.When I first started playing I didn't know how to save, so I kept my game on for weeks on its charger. At some point I almost beat the game, but one morning I left for school and forgot to plug the game back in.
I lost everything. Even my shiny Wurmple
