I think most of us have felt (feel) like imposters at times, you are not alone. Many years ago I had a dear friend who was in recovery, yet still found it very difficult at times to remain sober. He taught me one of the most important lessons I have ever learned. "Fake it 'till you make it." Read your bible, pray and talk with God, talk to your friends who know your struggle. Above all else, when things appear dry, do not quit! It's temporary and in Yeshua we are given the strength to overcome. He never promised us an easy road, just a cross he asks us to carry.
