16 months clean!! Im lost!!

I been doing amazing!! Fought for this and to get my life back together.. The past 16 months they been giving me Suboxone.. I have 1 left that will get me through tomorrow.. Than I am scared!! The pharmacy keep saying tomorrow for the past week.. I’m not sure what to do but if it’s not here tomorrow I know everything I built the past 16 months is going to be ruined.. Crazy to think they can’t get the pills in a week.. No biggie to them though but to me this can ruin everything I build in the past 16 months.
