Are there really many worlds? I hope not

Some interpretations of the many worlds version of quantum mechanics basically say any world that is possible actually exists somewhere or other. Whenever I think about this I see myself for some reason in a shower with Hillary Clinton and unable to get away from her. I know that’s weird but there it is. It’s also a reason I don’t want to go to hell, as I think it’s likely if I did, I’d meet her there, as well as a lot of other unpleasant people. Neither of these are reasons not to believe the many worlds interpretation but they are motivations against the theory at least.
