Do therapists get sick of working with clients long term?

I’ve been seeing my psychologist for around 5-6 years now and I’m starting to wonder if they’re just getting tired of me and want to move on. We’ve sort of spoken about everything now, all the trauma and symptoms and now I’m in this place where I’m just stuck and not moving forward. I trust my therapist and don’t want to move on and start over but I wonder if they feel done. It must be frustrating when a client is making no progress.
