I hope that someday you will get over some of your fears. With that being said, I have no idea if you've been abducted or not. But don't let it worry you too much. There are crazy things in this world that will drive you mad if you let them. Everyone has things that freak them out. Some of us just haft to work harder at not letting our fears take over our lives.
Now I want to address the UFO abduction thing. I think there are people who have been abducted, and is also one of the reasons why I think those beings are evil. They usually scare people, and perform strange tests, that emotionally disturbs the person for years. Interestingly enough, I heard one story where a woman got abducted and as the Alien was coming over to do a test on her, she started to think about Jesus. The Alien stopped and said "Please don't think about that" She kept thinking about Jesus and the Alien's left her alone. Do what you want with that story. But it sure isn't any stranger than all the other abduction stories. I think if that story really happened then that proves that they are demonic.
