If you attend a NYC public school, they are on break so seeing the GC this week is not an option,
I will repeat what jazzcastrophe’s recommendation that you go to The Door, tomorrow morning, (they open at 11 am) who can provide you with a referral.

DYCD programs
Crisis Shelters
Crisis Shelters offer emergency shelter for runaway and homeless youth up to the age of 21. The shelters are the entry-point for the DYCD’s Runaway and Homeless Youth system. These voluntary, short-term residential programs provide emergency shelter and crisis intervention services aimed at reuniting youth with their families or, if family reunification is not possible, arranging appropriate transitional and long-term placements.
For more information, call Youth Connect at 1-800-246-4646.

Where ever you go, get your documentation to take back to school with you on monday, when school reopens. Once you get back to school on monday, see your GC to assist you, with things such as signing up for free/reduced lunch (if you do not already receive it ) and assisting you with some things that you may need (each school district has a liaison that works with students in transitional housing).
Your GC can also work with you in providing documentation and contacting your college’s FA office and HESC to have your designation on your financial aid forms in order to change your status to unaccompanied minor, or to help you get dependency override/professional judgement.
