easy come, easy go

I’m getting back from dinner to face a short stack of 2100 chips. I
stacked a shorty to get as high as 6600 last level and then lost with
JJ on an AKx flop that I had to let go and with AK unimproved. I was
at aroun 4500 when I lost my key hand thus far. I flopped second pair
woth ATs on a board of KT3 with two of my suits. There were multiple
bets on the flop, on the turn of Ace and then just one on the river.
He had AK and left me very short.
With blinds at 200/400, I’m going to have to play for my stack in the
next 12 hands or so. I’m UTG+1 when we return. I won’t probably get
anyone to fold at this point.
I’m trying not to dwell on what would have happened if I was good on
the ATs hand.
