I like how your response implies you counter her during laning by team fighting.
Run where she ported from - hope you brought ghost, it was behind her minions.
Stun her - hope you can deal with the minion agro while you run to where she ported from. Good luck stunning her while silenced, by the way.
To pull it off you have to be aggressive. Actively try to stun her and get pot shots on her any time she moves up to last hit a creep. It takes two of her spells to silence you, so you should be able to get the CC off if you initiate the exchange. She hurts like hell though, so you need to at least match her damage. Putting a double stun or a support in her lane will help not feed her early.
Don't hang around under a tower at low HP. At lvl 9 she can easily combo you for over 1k. Every 20 seconds or so.
