Dear @Amani,
Welcome to the Wefugees Community and thank you for reaching out to us.
I am very sorry to hear that you are struggling since such a long time and you are even thinking about moving to another country. I assume with "applying" you are referring to applying for asylum again? You mentioned the Dublin regulations already - unfortunately, your chances to get accepted as refugee in another EU country (after getting rejected in one of them) are very low. However, did you learn already about the so-called "Chancen-Aufenthaltsrecht" which the new government is planning to introduce? Some federal states are actually implementing it already. Maybe it can also present a new perspective for you, as it is supposed to give long-term Duldung holders a residence and work permit for one year. In this year, the people might get the chance to fulfill other requirements for a residence permit (as securing the livelihood, prove the identity etc.) and eventually secure their stay in Germany. As I said, the law is neither finally drafted nor even implemented, but the chance is quite high that there will be improvements for people holding a Duldung since many years.
I hope this information are useful to you and please do not hesitate to get back to us with any further questions.
All the best,
Meike
