Hey Need4, First congrats on the 20 days! You sound like a whole new person. I am realizing that there has been a "cost" in my life for not getting into treatment sooner, but I also know that I can build a whole new life based, as much as I like, on parts of the life I knew before I started drinking alcoholically. You can too. I don't know ANYTHING about all the technical stuff you mentioned, but I imagine there are tools, even online, that can help you catch up with the technology changes you missed when you were drinking.
Sadness is part of recovery, for sure. But you can live a life that is beyond your dreams if you stay sober and work at it.
