I presume you did already contact your Embassy? They can issue an emergency passport quickly if needed.
"If you have an urgent need for a replacement passport and can show proof of imminent travel, we may be able to issue you a limited-validity emergency passport within 72-hours at the discretion of consular staff. Also, if no appointment is available, you may be able to appear during appointment hours without an appointment at the discretion of consular staff. It is recommended you appear at 7:30am Monday –Friday (except U.S./Thai holidays or the last Wednesday of the every month).
Please note: An emergency passport has only 5 pages, maximum 1-year validity, and is issued under special circumstances. The validity cannot be extended and pages cannot be added."
