Congratulations on Day 6 SSG.
I agree with Astro. My fear and anxiety in similar situations (often) are just about always unfounded. It is a real example of it all being "in my head", and the recent presence of alcohol.
It happened to me just recently. Beside myself with anxiety, but when examined and talked through no basis in reality.
This is only (yay) Day 6 SSG. Withdrawal will always produce anxiety. It really will pass. Maybe just speak with one of your customers to get the show on the road?
