alien abduction obsessive thoughts

i used to have this big fear of abduction thoughts when i was a little younger, and now the thoughts have come back again. i keep thinking that maybe i've been abducted by aliens and how i would never know either way. i try to force it out of my mind, but when i go to do something else, the thought pops into my head "why am i doing this when i could have been abducted by aliens"? has anyone else gone through something similar? i really need some coping techniques. :/

If you would never know either way, then how can it really affect your life? It's like a creationist asking how you can be sure God didn't just make the universe 5 minutes ago, or a solipsist asking how you know the external world isn't all in your head. Either way, it's the same universe, so why worry?

Gottfried Leibniz wrote:Although the whole of this life were said to be nothing but a dream, and the visible world nothing but a phantasm, I should call this dream or phantasm real enough, if, using reason well, we were never deceived by it.
