You're not the first person to have a fear of flying and you certainly won't be the last. I could sit here and wax lyrical about air safety but the best thing to do is to take a look at the safety record of your airline and the type you're flying on. The numbers don't lie:
The 787 fatal crashes rate (counted as a crash where at least one passenger died) is 0.0 per million flights. The A380 and A350 are also 0.0. None of these aircraft have cost a human life. The 747-400 is 0.06, which is obviously higher as the 747-400 has been around for over 30 years. Statistically, you could be born on a 747-400 and fly on it 24 hours a day until you died at the age of 80 from old age (around 700,000 hours) and you'd need to be on the thing another 250 years before you'd even be in with a chance of it crashing on you.
ANA have a very good safety record too, with the last fatal incident a mid-air collision in 1971.
However you travel, you'll be fine. The part of the journey in which you're most likely to die is the transfer by road to and from the airport.
Hope that helps.
