I need to break a lease and i dont want to pay the rent.

The E-mails may have been sufficient to form an agreement. Since it is near the end of the month and your opportunity to give notice may be now, you should promptly have someone review this and get advice. Either consult an attorney familiar with landlord/tenant law, including local ordinances, or seek out a landlord/tenant organization that may be able to offer some guidance. Proper notice will help you limit your liability for months beyond what you may already be committed to paying.

If you are in financial trouble overall, I suggest you consult with a bankruptcy attorney. I recommend you assemble for legal consultation: (1) your income information for September through February, including wages and unemployment during that period; (2) all your bills (several months' copies neatly assembled); (3) last four years' tax returns; (4) a credit report; and (5) other information that may apply, such as copies of lawsuits. Set up an appointment at your earliest convenience to afford the most opportunity in which to be advised about your best course.
