Just getting sober is a huge accomplishment and a huge stressor. A new job is also a huge stressor. Try to stay in today and just deal with what's in front of you and be patient with yourself. You have a lot going on!
Speaking personally, the time I most wanted to drink was when I was feeling overwhelmed. I had to learn to let some things go in order to stay sober and not let myself indulge in worrying (still working on that one!).
As long as you don't drink, you're moving ahead, I promise......Things will work out.
