Mary,
What you are feeling is normal for where you are. The fog is starting to lift, but we don't necessarily like what is revealed. Take it one day at a time - and remember to identify, not compare with the things you hear in the rooms. Make recovery a part of your daily routine, and watch out for H.A.L.T.: Hungry, Angry, Lonely, & Tired. Those are the times when we are prone to relapse.
Good luck, and congratulations on 15 days!
