Tilted and raged so hard I actually uninstalled. Please give me advice!
72% normal win rate on my level 25 smurf account.
Been almost exclusively playing Wukong/Fizz
Regardless of lane opponent I can

Checking my match history, there are few matches I feed and I'm able to carry most games. My friend's list are full of diamonds who are waiting for me to get level 30 so we can team up in ranked.
I've improved my overall score (KDA, vision, win rate, cs) and almost always completely crush my lane opponent. I know that really isn't saying much as using Fizz/Wukong but in/out champions are my favorite).
So where do I need help?
I still have absolutely no idea how to deal with
