I'm sorry you're experiencing so much anxiety.
For me, it's better living through chemistry. Which means I take medication for anxiety.
Anxiety, which I didn't really realize at the time, was at the core of why I drank so much for long. I have generalized anxiety disorder. I see a psychiatrist for this.
It's been ten and a half years since I've had a drink, so I know the alcoholic hangovers weren't the only thing causing my anxiety. Thing was, as I think some of us here know, alcohol masked the anxiety while I was actively drinking. It did a good job of it, too. Until I became addicted to the alcohol and suffered the nightmarish hangovers.
Have you thought of seeing a psychiatrist, or even talking to your G.P., about your anxiety?
Maybe they can help.
I wish you the best and hope your anxiety clears up straight away. I know what it's like to suffer through.
Best to you.
