Hello!
The way I've gotten over a lot of my initial anxiety is to really push my comfort zone; which when I was started was practically everything!
Of course if you're scared of heights you don't go straight to the 10m diving board, you start at the 3m one... sure, it's still scary, but it's something you can handle. Eventually the smaller things that used to cause you anxiety cease to exist as you become accustomed to them, at which point you can start moving on to the larger things.
So basically lean over your edge, but don't go jumping over it. I forgot the quote, but it was something like 'the journey of 1000 miles starts with one single step.'
Also remember, fear is growth waiting to happen
