My Medicad was cancelled by accident. I went to fill prescription & was told as of March1 it was cancelled.How long before I can get my meds?

Disabled but work part time, me and my new born was cancelled somehow by someone other than me, but my fifteen year old is still covered. Is this an easy fix? I'm a Suboxone patient and already going through withdrawal. So I need meds within a day or two, otherwise it could lead to death and cost $1000 for the script.
