Why does my nose look like this? Is it possible maxilla & mandible will go back way it was?

I got Botox in masseters twice first time was great then got it again n 5 months later i looked aged smaller chin nose tilted down crooked nose my face looks like a mouth breather as i did my research. I look funny. As i look to side i notice how bottom of my nose tilts down. Everyone else's is straight across to lips but not mine. How can my whole bone structure change after 2x only. Its been year later n my masseters are huge again but face still looks funny
