How do you get over ranked tilt?

I know its actually a 'balanced' thing where sometimes you just get unlucky and sometimes the other team gets unlucky and if I'm losing a lot its 'probably my own fault and you need to stop flaming other people'. But how the hell does one get over ranked tilt when they get unlucky and play 5 games in a row with each one having a lucian who thought he had challenger mechanics and build zed's core build to play like an assassin and ended up going 0/8, an ekko who died twice and didn't realize he should play safe so he ended up going 0/11 before 20 minutes, an afk, a person who disconnected and reconnected consistently in every single teamfight (Not their fault but really frustrating) and worst of all, DYNAMIC QUEUE making me play as a solo with other solo players against a 5 man team on skype. Right now I just want to say goodbye to ranked and have good fun in normals, but I enjoy the sense of achievement when I rank up, and the progression system so I can't. Does anyone know a good way to just reset entirely and forget those infinite loss streaks that were entirely out of your own control? Don't take me wrong, if I mess up, I know it and i don't tilt because i take it as a way to improve, so this is exclusively for feeling like everything is pointless because its all a roll of the dice in champion select.
