What do you do when....

Your support rage at level 2, then decides to call you trash.. a teamfight happens at lvl 4 which you try to get into and get there just as it ends, and the team then rages that you're a trash adc.

This is in ranked btw...

Because we all know if I don't stay bot, and roam top with my support, or mid who isn't even pushing towers, and we let the enemy bot take all the towers, everyone is gonna blame me..

If I stay, like I did and do my best to defend the tower as long as possible, and get tower dove 1v3.. They'll say I suck anyway..

Either way my team tilts off the face of the earth and I lose...

So what do I do to fix this problem..
