First, play with some one who knows main Top laner.
Means, play with someone you know is better than you, play vs him again and again and again.
Two, make a different game play, you see he's attacking you, let him attack you until you know you can win that 1v1. make it more 'harder' for him.
Play mostly vs your counters and learn they game bars/plays (how you can beat your counter) and so on.
good luck and have fun!
Thanx
