Exposure, exposure, exposure. The idea of having an interview is scary (I had an interview just the other day), but it's even scarier to have to go each day without facing your fears. I was scared, nervous, palms were sweaty even the day before, and I knew my face was red the whole time, but I went through it and it was much needed exposure.
Take a look at what staying in your comfort zone has brought you, and place that weight on one hand. On the other hand, hold all the things you wish you had done were it not for fear and anxiety. Life won't wait for you, you have to put your shoes on and just go and live, knowing you deserve all the things you want to achieve and only you can stop yourself from achieving them.
In short, it's not about coping, because coping basically means "how do you deal with [something negative]?". You deal with it by making it positive, by making it work in your favor. Change fear into excitement over doing something new and daring. Take anxiety and turn it into an adrenaline rush over the fact that you're experiencing something new. Flip the bad around in such a way that it becomes good and helpful.
