You need to share more info. What do you think about the business in general? How your co-founders feel about it. Are you all at a point of wanting to call it quit because you don't believe in it anymore, or is it simply the debt that makes is all seem like a bad movie.
You need to be honest about the business. Selling a business when all founders want to get out is HARD if not impossible. If however, at least some of you want to keep at it, you might consider selling your shares (or part of it) rather than the entire business.
