Uneven facial symmetry. (photos)

I've always notice i have a uneven face and i feel very insecure about it. I like to know if is there something that can be done to get it even again. I've done a lot of research myself and i definitely noticed how my my bigger side has a larger masseter muscle than the smaller side. I've tried to chew with my smaller side for a while (couple of months) and nothing seem to change. And also when i yawn my smaller side hurts or makes popping noise (occasionally )
