Altered, I was in therapy 1978-1987 and 1996-2005 with the same therapist. The first 9 years I was just standing still like you describe but oh, how difficult that was! Therapy at that time kept my head above water and that's about it. But if I hadn't had that therapy I wouldn't have survived.
Perhaps PC is like that for you. You don't see yourself moving forward but you also said you don't see yourself moving backward either.
