Asking for advice on how to keep myself from dying so much and to control my literal blood thirst.

One thing that Iv'e noticed about myself is that I always die too much. Even when i'm doing well I find myself getting too cocky or going too ham and end up dying a lot more than I should. Of course outside of the game I can look back and say that was a dumb decision I shouldn't have done that but when I am into the game I'm kill thirsty as a motherfucker and don't care about the death.

I want to ask you people how you deal with this and quell it. I feel like it would improve my winrate significantly if I just learned how to stop dying so much.

This is especially bad when I play support because all I want to do is engage, engage, engage and pull the kill trigger but it's almost never the proper time to.

My favorite champion hands down is Jinx and she's the biggest reason why I decided to main the adc class because she satisfies and synchronizes well with my go-ham-and-don't-give-a-shit-about-shit attitude when playing. A few other champions like Garen and Leona do this too but I think the worst way this attitude is affecting me is in the support role. If you look at my match history everytime I play support I lose and usually because I feed hella hard.

So like I said is there any advice that you guys could give me to make me stop this thirst.
