VPN is normal because it just adds lag. If you're on pc, go download a game on Steam and play graal. It has the same effect. I'm not saying I can beat her, never implied it, but if I lost I wouldn't make a thread about it.
My personal advice is to find a close friend of yours who does indeed lag, and practice with him/her. It helps hone prediction skills, and then you can go beat her and the problem will be solved at it's root
