Hi Bitten ~ I'm a recovering alcoholic. When I got sober I felt much the same as you do. And I was on an antidepressant too. Life all of a sudden was REAL, where it wasn't before because I "medicated" it. Now, I had to face life on life's terms.
Yes, I was anxious. But I was also excited because it was a new feeling! All of a sudden I was responsible for my own actions for the FIRST TIME in many many years!!! All of a sudden I had to answer for my actions. And all of a sudden I had to go to work SOBER!

I had been showing up hung-over for so many years and now I had to make it completely clean. It was all NEW to me.
Life was new to me and it was really scary but exciting. Try to look at it as a new journey! This is something you probably haven't felt in a long time -- CLEAN & SOBER! Enjoy the feeling! Try not to think of the anxiety.
I wish you a GREAT journey! God bless and please take care. Hugs, Lee
