That's happened once with me, too. It's because you taught that Pokemon an HM.
I'm most certain that depositing and then releasing is the only means of releasing a Pokemon. I think it is this way so that you don't accidentally release one of your Pokemon back into the wild as apposed to being able to simply release your Pokemon in the same area you can switch them round and attatch items to them
you have to go to the pokemon store and heal all of your pokemon then it will be back to normal
Then you have failed. Latias comes back actually.
Stats do change back to normal after you switch out Pokemon. This isn't always a good thing to do because then your opponent grabs a serious advantage. My suggestion is to switch to a Pokemon that won't really be affected by the move that your opponent just used and is most likely to use again.
In the event of releasing your Starter Pokémon in Pokémon games, it will be released back into the wild but you will not be able to encounter it at any point during the game. Your released Pokémon will be gone forever.
If your referring to releasing them in Pokemon ranch, then you can always bring them back.
It dissapears then comes back.

You can't unless you saved before you released it in that case you can turn it off and it will be back in your party and you can go on as normal.
