You need to speak with a bankruptcy attorney in your area. Many attorneys offer a free initial consultation. Take advantage of this and discuss your particular situation with someone who can help you.
Generally, taxes owed to the IRS cannot be discharged in bankruptcy. There are exceptions but they are limited. This is why you need professional help. You do not list any other debts. If the only debt you have, other than to the IRS, is the $6000 to the school, bankruptcy may not be a particularly advisable option.
