Hi Mat,
First off, congratulations! That's awesome!
I'm on my sixth night of sobriety, so reading your post was like talking to yesterday me. I have also felt this kind of surreal am-I-on-something experience the past few days. It feels kind of like my head has been filled with water and is slowly draining out, which I realize may not make much sense. I'm also looking to see a professional to help deal with the depression and anxiety I used drinking to medicate. Please let us know how that works out for you.
Just want to let you know that you're not the only one scared to let themselves feel too good about their sober time. I think it's a healthy and normal reaction, and might sustain us until we can trust ourselves a little more. Personally, I know I'm walking a fragile line so I'm trying not to get too ahead of myself and feel overwhelmed.
Abby
