Dear @Lindneregng,
Welcome to the Wefugees Community and thank you for reaching out to us.
First of all, I am sorry to hear about your struggles and that you already wait so long for the results of your asylum application.
However, in Europe there is a policy applied called "Dublin III Regulation" - it determines in which European country your asylum procedure must be processed. Unfortunately, asylum seekers can not "choose" the country freely.
I highly recommend you not to withdraw your case, especially without having discussed this with a lawyer. For the time being, you may also contact a refugee counselling office for support (the so-called "Asylverfahrensberatung"/asylum procedure counselling) would be the most specialised service. Together you can apply for taking insight to your BAMF-files to understand at what stage your case currently is.
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
Meike
