Help fix me?

Stop second guessing yourself. Hesitation begets weakness.

Fixing someone requires a good urologist or a vet.

I'm just at a loss as to what to change. Do I play more aggressive champs? Never let myself support? Only look for the snowball? I feel like I have all the game knowledge, but get stuck watching the ship burn down around me. Is this unbelievable luck or am I just awful at this game?

Yell your name as you engage.

Maybe take a break, focus back in on your fundamentals. Everyone has losing streaks

EDIT: I just looked up your op.gg; you're on a 2 game losing "streak". Honestly it's difficult to say what you should change when I don't have any insight on how you're actually playing. Honestly though, focus less on winning, focus more on correcting your mistakes and improving as a player and you'll naturally win more games.

Thanks for the moral support guys! By brutal I meant I think I had lost like 15/20 or something of that ilk. I've been playing much more aggressive and trusting my instincts. 2-0 Let's keep the streak alive, lol.
