I’ve never had bad acne in my life here and there I would get a few spots but recently my whole face has broke out badly and I’m not sure why 😕

Could there be any reason for this happening ?

My parents thing it might be a withdrawal because my whole life I’ve had a addiction to fizzy drinks and would never drink anything else and 2 months ago I gave it up and they think this may be what’s causing it but I’m not sure 🤷🏻‍♀️
