The League Flu

So there's this sickness going around in my area and as you might guess, I have it. Bad head cold, sinuses clogged, minor headache, but most of all this, off... feeling..

I feel like it's hindering my ability to make decisions during my ranked games. I've been playing worse in situations I knew the answers to. I just, don't feel as alert as I normally do. My family has it too and they say they have the same feeling.

Anyway, the season ends in October and I want the season rewards. I need to get to Gold 5 from Silver 2 and I'm running out of time. What am I going to do? I know i'm not playing at my best, but I'm running out of time.
