@podeena Really sorry to hear about your issue. I have a close friend who faced the exact same issue as yours, though he had applied for a fiance visa. He had the interview in March 2020, and his passport was not returned, and after waiting for almost 2 years, his fiance had to file a mandamus suit, and he finally got his visa and passport back in October 2022.
I really do pray and hope you get a positive response much sooner and hopefully before the medical expires. Just wanted to give you that context so you are prepared to reach out to a lawyer to file a mandamus if god forbid it is needed.
This is why I was urging everyone who has the means to transfer their cases because anything can happen with the Islamabad embassy.
