Bankroll pretty much destroyed!

I've just gotta soo many coolers and bad beats in a row its untrue.

Lost $1600 going all in with aces pre-flop and getting called by K's and him hitting AK on flop.
And god knows what else i lost things to!!

Need my bankroll up high again aaarrgh!!
Think what i did wrong was play 6max because there were no full-ring games going on, i hate 6 max!!

decided to take out $1k so now my roll is purely profit.

Bankroll: $5818
