Dealing with tilt (Help please)

So recently I've just been having a bunch of bad games. I've been mainly playing Tristana Bot but haven't been able to do anything in games, let alone carry. When I first started losing games it didn't bother me as much but now even small things like missing a canon can immediately put me in the wrong mindset. I'm just wondering what advice everyone has to deal with tilt and staying in the right mindset during game.
