How long since your last drink? If you're addicted to the drug then yes, it would indeed calm your nerves - for now, until the withdrawal starts all over again... We call this the "jumping off point." Can't live with it, can't live without it. The problem really isn't that you are anxious as much as you need a drug to calm your anxiousness - a drug we know to be extremely addictive and dangerous. It's a tough spot, and should you decide you want to not drink you'll need to take action towards recovery in some way.
Posting here was a good idea and a good start! Is there someone else you can call as well? Seek out a meeting? A good, sober friend or family member? A therapist?
If none of these is an option, consider preoccupying your mind - go for a walk, do some household chores... something that will get you moving. When I was dying for a drink, movies, TV and reading didn't work because my brain was squirming, but chores like window washing did the trick long enough for the craving to pass.
One of the biggest lies we tell ourselves is that a drink will make us feel better. It doesn't - it's just a simple fact. Hang in there
