My lips fold when I talk. I look weird and also fat saggy cheeks. (Photos)

I'm 21 and everytime I record myself I see that my mouth looks weird when i talk. Sometimes it's even not only cosmetic but also stops me from properly pronouncing words. I work in the industry where I have to constanty talk on camera, so that is why I need to get rid of this. I had a consultaion with one of the best cosmetic surgeons in LA,with a neuropathologist and a dentist. None could tell me whats wrong and how to fix it. Did lip fillers before, didn't seem to change anything.
