Broke My Break from Drinking

So I was on an amazing (to me) streak without drinking. 12 days, no alcohol. I was proud of myself. Then yesterday I went to the liquor store and was looking at NA options. But ended up getting a six pack of Corona, and vodka shooters (I haven’t opened these yet). I’m on my period so my stomach got incredibly upset with me… I feel so much shame. I’m not part of any program and haven’t told anyone about my break. And it’s not like I binged the beer. I had three last night, and didn’t feel more than a buzz. And the shooters I got bc I’m traveling this week to a place I’ve never been before. And I am terrified if something bad happens, and I don’t have at least a little bit of a drink, I will just ruin the vibes for everyone. I tend to be the supportive, kind, funny friend, and if I’m not “on” or the sadness takes over I am afraid I will be just dull and sad and make everyone else suffer. And I’m not going to get blasted I just need it with me. Does anyone understand? Anyway I don’t want to shit myself so won’t be drinking for at least a couple days…
