You can do this! You've already made a better choice by making a cup of tea. I hope you don't mind but I did a quick search and it looks like there may be an online meeting group that you could look into, I've added the link below but didn't really read anything on their site. aa-intergroup.org/
To me you are already taking a step in the right direction. You can always find help here but remember most of us aren't professionals but will lend an ear and an opinion if asked.
Have another cup of tea, take a deep breath and know you're the one in control not the beer.
