Do yourself a favor -- don't go down the bankruptcy path too soon. Speak to a good lawyer first and try to get things resolved. Bankruptcy has long-lasting consequences, stays with you in some form for the rest of your life and should really be avoided unless absolutely necessary.

Since you're a student (didn't know your age when I wrote my other comment), it's even more likely that they have no intention of actually following through with the lawsuit, so rest (slightly) easier knowing this will likely cost them more $$ than it will cost you.
