Help me with my downswing.

[macawboy]

I am playing small stakes PLO8 Turbo sit n goes and after a good start with a ROI of 15.4% after 469 games at $6.50 stakes moved up to the $16.
All went well at first building up a nice bank roll .Then the dreaded down swing happens .I have only had one first in over 50 games and over a period of only 160 games hit a 45 buyin downswing.
I believe leeks have crept into my game and now i feel like i will never have another winning session again.Should i take a break drop down a level are just carry on .
Also after a bad beat i have started to go on tilt.
Any advice please before i give up on the game i just love to play.
