How to stop a losing streak or massive tilt?

After going on an insane 13 game winstreak, and skipping divsions all the way to Silver 2 I am now stuck in a rut. A 5 game losing streak has halted my momentum and desire to play.

I'm really tilted and can't seem to get rid of the negativity. I tried to take breaks, go on walk ,etc but come back to see the same defeat screen.

What do you guys do when you are on massive tilt or losing streak? Should I just take a 2 week break? What happens if my mechanics start to drop?

Im so close to gold 5 I can feel it. I want to badly but can't help but cry when my team consistest of a qualifing player, 2 bronze, and a silver/gold that has 20+ kills and we still lose.
