Hi missing. I had signed off when you posted, but want to commend you for coming here and talking it out.
As everyone's said, this is completely normal for the early days of recovery. You're doing great reaching 27 days, especially after 15 yrs. of heavy drinking. I drank all my life, and definitely went through a grieving process. I felt very sorry for myself in the beginning, felt there was a party going on and I was missing out. That's a lie. Picking up is dangerous and leads to misery. You know that, though.
You are doing great & we're proud of you.
