HELP: How to come off tilt

I'm currently on this major tilt, went from SV to S1 going to gold series in a week and now iv'e been relegated to S2 and slowly going doing further. Whilst in many of my games i'm not the main player making mistakes it's not to say i'm not making any. Anyway, i just wanted to know what you guys do to relax come off tilt, i played some normal with vayne to try and boost up my 'mechanics' just in case that was what was wrong, i take breaks between games etc but nothing is working thus far. Would just like to hear what you guys do in my situation, thanks in advance.
