Welcome, mewithoutYou. It's great to have you join us.
Yes, I've felt that way a few times. I think it's very common to feel vulnerable & not quite trust ourselves. The last time I got sober it really was the last time (11 yrs. ago). I had done so much damage I feared for my life. I had been sober for 3 yrs., but became a daily drinker when I relapsed. Talking things over here helped me not to feel alone. That meant everything.
Congratulations on your 2 sober weeks. We're here to encourage you, & we know you can do this.
