Yeah, don't pay attention to that voice. It's lying to you.
It wants to drag you back down to that hell hole. And do keep on keepin' on - sober. It can take a few weeks to start feeling better, more normal. Do'nt give in and drink, it'll put you right back at square one.
Eight days is still very early recovery. Don't give up now. You're doing great. Stick with it!
