You have 90

invested in other games, so once you are eliminated from the one game you speak of, you'll get 10

back to bring your total points back up to 100. But your available points would still be only 10.
However, if you stop showing up in a game, your country will go into civil disorder and it'll show you as having Left. But, because you technically are still in the game, you don't get your points back.
So the only way to get your 10

back is to be eliminated. But you might as well stick it to the country/countries that caused your downfall in the first place. Try to make them regret turning on you. Talk to the other countries and see how you can help them against your enemies.
