Hi Mohammed, normally your lawyer must give you advice and prepare the interview with you.... you must tell the court essential (and true or validable) reasons why they should not send you to bulgaria. Unfortunately that can only be problems with your health, problems like traumas or something similar. Ask your lawyer. Here are some Informations in germen, may be you find someone to explain,
good luck to you!
