H1B Emergency appointment (Dropbox)

Hi all,

I have to travel to India since my mom has a heart condition. I have about 45 days off. I see I qualify for dropbox and there are no appointments for stamping h1b. What are my options here?

I called the consulate and they said i can’t get an emergency appointment since i qualify for dropbox.
when will dropbox appointments be available again? When can i realistically be back?
