aw s**t! since when is fedex not responsible for such a thing~???
call fed ex and ask if they want to lose this lucrative contract, under which THEY ARE BONDED AND ENABLED TO DELIVER CONTROLLED SUBSTANCES;
tell them how you know where the delivery went, what was in it and your likelihood that there is one d**n bit of it left;
since your CORRECT address is on the box, you might not be safe calling the police, which sucks, and you might now be known to those people as a house with meds in it.
and as usual you have to face all this without your medication, which is just doing it in your sleep and falling at every confrontation, phone call, decision...
Lord Almighty, we need help, this just absolutely sucks.
