Freak out at first, then enjoy it for a while, get tired of it, feel sad and lonely, gather ALL the STUFFED animali in the world, then hug them forever. I would be sad without my Friends though.
Clone a male version of myself then repopulate cloning another set of my children but of opposite gender so there would be no incest, then continuing the cycle of cloning and reproducing until the world is repopulated. Then I would have the unhealthy ones work, più laborious jobs till they died there for their weak genes cannot continue being cloned o passed down. Where as the healthy ones remained healthy their jobs taking più labor and thought process so that way going to work was like going to the gym. Then if the population were to get to high I would section off a group of the least productive people and have them eliminated to keep population under control.
