Welcome to SR, LeTheVerte. I am glad you are here. You have made an important first step by coming here. Your next step is to do exactly what you said: Don't drink today. Then, tomorrow, come back to SR, read some more, and go from there. If you can make a plan and stick to it, I promise you that the fear and the anxiety will subside.
Good luck on your sober journey. You are doing the right thing.
