See picture: Hero is BB sitting with TT, folds to HJ who is big stack and limps (been aggressive stealing dead pots), CO and short stack jams 5.7 (7bb)(lost most his stack on a flip about 4-6 hands prior), BTN and SB fold, now on hero to act. Need to call 4.9k into 8.15k still with CO big stack to act behind. A call would leave hero with 18k behind. What do you do and why?
