i just made a mistake, how bad was this one? 30/60 pstars hand

[J.Brown]

Here is the breakdown.

Very good game I am in late position with 87hh, early position raises, 3 people call in between, I gladly put my $60 in. Button calls as does the BB. So 7 of us take the flop. $420 in the pot.

Flop comes 953 rainbow. Checks around!!!!! Can you believe that one?

Turn comes J. No flush draws. Checked to me, I fire. Button raises, BB 3 bets, mid-position caps it.

What do you do with this double gutter?
