I am becoming toxic.

So, as of in the last few games I am feeling like I am becoming toxic. (I don't get all toxic without a reason and it really takes some skill to get me to it) but the league community did it, I have been playing blind pick since my friend is low level (I usually play draft). So what happens usually is: I call out JG, somebody else keeps spamming jng. I call out Top: somebody else keeps spamming top I call out mid : same thing Now, note that this doesn't happen all in one game and if someone calls out lane before me I will give that lane up no matter what, And so, after a few tries to convince the person to give me top, mid , etc. I Become toxic, I am so incredibly frustrated that people just do what ever the **** they want and I am forced to give up my lane because i care about winning. And in some cases Where I am having a really bad day, Ill just start spamming my own way, and going "give me top or i feed" and ETC. How do I prevent situations like this happening?
