Buggirl,
You should be proud of the things you have achieved, you're doing great!
Not really related to drinking, but I have pretty bad anxiety and last year, I didn't leave the house for several months. One day, I walked to the end of my road and a day or so later, I walked to the shop and bought a bag of crisps.
It was the hugest achievement for me and I would be panicking, sweating and freaking out. But my therapist called me after I'd had that first trip out and she was so full of praise and excitement for me. I felt truly proud because she understood how huge it was for me!
Unless someone has been there, it can be hard to understand but as you know, it doesn't discount what we have achieved :-)
