Help please yasuo

So i have no idea how to play as yasuo. Um how does one lane against leblanc with yasuo i guess thats a start i always get destroyed by her. i try to farm but she freezes lane and i block her marker but then she waits to get the snare and 100-0 me. she is ranged so tons of harass and whenever i commit she bounces back to marker so if i cant win this lane how exactly am i supposed to leave the laning phase with least deaths possible in the least
