Welcome to the Wefugees community and thank you for sharing your situation with us.
At the Frankfurt airport, there is a special asylum procedure. You will find more information following the link to this website.
Apparently, there is also a refugee counselling contact person at the airport itself. You can call them for help or ask the authorities to support you in reaching out to them.
