Firstly, well done for recognizing the problem and addressing it. This is the right decision.
I am almost 11 months sober now and it was the best decision ever.
Try and see it for what it is, something that is making panic and anxiety so much worse, so that you can come to hate it and never want to drink again.
Find healthy hobbies to distract your mind. Painting and drawing is a good one, even if you are no good at it. Or photography.
Mark each day off on the calendar so you can see your accomplishment and be proud of yourself.
Remind yourself that there is no such thing as "just one drink"
It will get much easier as a month or more goes by.
Keep posting here as you progress and receive encouragement.
Congratulations on taking a very big step towards a better life. Keep up the great work
