Good job on not picking up TD. Have you ever spoken to a doctor or psychiatrist about your depression? Many times underlying psychological problems were factors in our drinking- and they don't go away when you quit drinking. AA/SR are great for recovery, but depression ( if clinical ) is a health issue and should be assessed by a health professional
You have come a long way, 5 months is great! Don't let an underlying condition drag you back into the cycle of drinking to escape it - because you already know what the result will be.
