You are far more likely to crash whilst driving to the airport than you are flying. The chances of your plane crashing is astronomically small.
And if that doesn't help then this might, 96% of people involved in plane crashes survive. Even if you're involved in a plane crash, it is extremely likely that you will survive.
Quite frankly I would be more worried about getting out of bed in the morning as it is more likely I'll die doing that than flying in a plane.
