There are some really good "fear of flying" groups out there. Phobias don't have anything to do with logic. I watch those Aircrash and Seconds from disaster all the time. I used to be on a safety committee and went to a crash site. I do trust the pilots and their training. That's why there is more than one of them up there. Sometimes the fear has to do with an unrelated event in your life, not having a sense of control.
I just avoid older aircraft. Pay attention to that stupid safety briefing and study the card and memorize where the exits are. Mentally practice how you would evacuate. That gives you a feeling of personal control.
Take a pill.
