You DO NOT have to win lane....
But for fucks sake stop going 0/9 when you're playing top/mid/whatever. Maybe after the first 1 or 2 deaths you should realize maybe it's time to farm or wait for ganks, freeze the damn wave. If you see your bot lane doing great, the adc is 5/1 and the support is helping him while they have the wave pushed to the enemy inner turret, do your part and just get carried by not getting yourself killed. If that's just too hard then don't call the ADC shit since he can't carry while getting one shot by the people you fed.
