While I have always been an optimistic person of good cheer, the voice of doubt nevertheless sometimes sent out loud messages to keep me 'real' and focused. Then, of course, the voice of 'relax, your doing just fine, you're figuring life out' would counter, and encourage me.
I suppose that is the great balancing act that encourages us to love ourselves while discovering and attending to what needs shoring up.
I worked as a co-counselor in a psychotherapy practice for almost ten years during the late 80's and 90's. I noted that both voices seem to sit one upon each of our shoulders. For most of us, both voices want the best for us. But the critic can be very harsh in its approach, depending upon the individual.
Well, anyway I've survived my critic thus far!!
May you all survive yours. And may your 'cheering section' cheer you on eternally, my friends.
