Dear @Khan,
thank you for sharing your situation with us.
you could go in Berufung but your lawyer has to that and explain thre entire situation. Another option would be apply a second time( Folgeantrag--> at the BAMF) and argue thatdue to the health situsation the fact around your case have changed.
If the second case is rejected than you can appeal.
I hope this can help you, if you need further guidance please do not hesitate to use the community.
Best regards,
Nilab
