Please Call Me a Girly Man (second stack v big stack)

Full table. ITM. Average stack was like 15-20k. I'm second stack at my table 31k. Blinds (800/1600). Big stack villain is SB with 53k and has been playing too tightly preflop, so I've been stealing the blinds very liberally. I don't remember any hands villain played postflop, as his preflop raises tended to get respect and were infrequent. BB is super-tight with 8.5k (he plays in every tourny I play in, and I love to see him at my table when the blinds are big). Other stacks at the table are all <10BB except for 1 20k.

Folds to me in MP with 9To. I make it 3.6k. Folds to big stack who calls. BB folds (I love this guy.). Flop comes 973r. Big stack bets 4k. I vomit and raise to 10k. He miniraises me. I vomit. I vomit again. I fold.
