Congrats on two weeks and welcome to SR!
For me, I had to remove myself from my old environment, old friends and old life. I couldn't be around booze at all for several months. I just hit one year sober, and I would never allow myself to live in a house that has alcohol, precisely because of the things you said: those late night cravings and depression and feelings of loneliness.
I don't think I really started to live a normal life until I changed my life to make it conducive to long term sobriety and recovery. Whenever I tried to live my old life but just remove booze from the equation I was miserable. IMO, getting sober is a lot more than just quitting drinking. It's a change in lifestyle. My whole life was organized around drinking, so in order to feel any real change in my life I had to completely reorganize it.
Best wishes,
