Minecraft: good at pvp but scared of mobs?

When I started minecraft I didn't have earbuds so I didn't hear anything. I would go on a server and do survival games. I got good at pvp and now that I have earphones I can hear other players coming.
I started playing survival recently and when ever I hear any mob I freak out and have to close the game. Can someone help me get over this fear

You can turn off mob sounds or simply play on peaceful

Take out head phones when on survival? Maybe just try doing it a bunch. Start by playing in light areas letting mobs in and just keep getting darker? I don't know just ideas
