Lots of good advice here Igres, glad you came back to seek help. Recovery is a physical and mental thing. It took me several months to start feeling better in some areas. I also found that I had underlying anxiety issues that I had never dealt with all my life so I'm dealing with those now too - quitting drinking in itself didn't solve that problem.
If you know your testosterone levels are normal I"m assuming that means you've seen a doctor? If not it's not a bad idea to get a checkup. Don't rule out psychological factors like depression and anxiety either, and remember that those issues are very treatable so seek help from a therapist if you feel the need.
