Hi @GirlFromStore and welcome to the forum. 
Congrats on taking the first big step.
The good news is that you are young, and have a whole sober life to look forward to once you quit! …Unlike some of us who wasted decades drinking and now look back with regret. Working in a liquor store is certainly a challenge, but there are people out here sober who work as bartenders, in restaurants, dance clubs, etc. It is doable!
Here is a useful thread on getting through early recovery:
