You dont really ever get over it, but as time goes on you begin to realise that there is nothing you can do about it and that everybody dies at some point.
In your position you’ll get to see a hell of a lot of people who die in all sorts of circumstances, maybe try to use some of the memories from that to develop or change your perspective on death. It might work for you, but again it might not – everyone is different apart from that one thing.
