Want me to tell you why I put down Pokémon for several months and haven't picked it back up again until yesterday?
My 3DS had busted last July, so I got a new one and performed a system transfer.
And then...
"A communication error has occurred."
My internet crapped out mid-transfer. All of my save data was lost. All of my pokémon were dead in an instant. It had gotten my eShop data across successfully, so I could redownload Y and start over if I wanted to, but I just didn't have the heart for it. It hurt too much.
Okay, you win. :( There can be no worse luck then loosing your save data. I'd feel exactly the same as you do, no doubt.
