Big overbite I’m unhappy w/. Dr said he can’t move top teeth back more because I didn’t wear bands enough. Is that true?(photos)

I never had this overbite before orthodontic treatment. My orthodontist said he can’t move my top teeth back anymore because I didn’t wear my bands enough earlier in the peace is that true? Surely not! I never had an overbite before braces and I’m not happy. I feel like I have to physically put my lip over the front of my teeth to fully close my mouth.
