Well, if they all had you covered you were probably short-stacked to begin with. I think folding vs. calling depends on you, whether you were happy for a min cash or you wanted a deep run. Your odds of winning are significantly decreased by the number of players in front of you, so folding is just fine imo. However, if you wanted a shot at the big money, this is probably your best chance. I would call and then puke when I got knocked out. I hate that sickening feeling of losing "too early".
