Down swing - Varience ?

Okay, so lately I've been doing quite poorly at the $16 SNGs.

I think because I was trying to 4 table again, which somehow automatically 
puts me off my A-Game. 

I then wasted another $50 playing NL 200 shorthanded. Which is so stupid of me,
and then I wasted another 400$ on NL 600 shorthanded.

So I decided to cash out my remaining bankroll, and take a break for a couple of weeks,
perhaps catch up on some reading. I still haven't finished my 3 Harrington Volumes.
