I have had a few anxiety attacks - both as an active drinker and even as a sober person. There's a good and fairly active Anxiety Forum here on SR that also can help.
As for the "stages", it definitely does get better. In my case, I saw a medical professional (took me 1.5 years of sobriety to get the courage) and started some low-dose, non-addictive meds. The doctor visits, plus learning how to manage my anxiety have helped greatly. I've been able to do things like attend my grandmother's funeral, travel again, etc - events that seemed light years away during the dark stages of early recovery anxiety.
You can get through this, but don't suffer needlessly. Suffering constant anxiety and not seeing a doctor is like having an infected leg and just letting it rot. Surely you'd see a doctor for your leg...make sure you see one for your mental health, too! Right? There is help available, don't forget that.
