6 months after masseter Botox. Will my face ever go back to normal? (Photo)

I got masseter Botox back in December, they told me it was temporary and would only last 4-6 months and it would be back to normal at 6 months. I asked for the MINIMUM. My jaw line completely disappeared. I had no jaw. Now my face is coming face in a completely different shape (chin is shorter, its asymmetrical, no structure like before and the jaw appears much shorter too, seems like I have lost volume in my face now whereas before I had plenty). Please help I’m so scared
