My bottom midline does not align with my top midline, I've had braces for 4 years, any advice? (photo)

I have had braces for nearly 4 years now. I started out with spacers then an expander then the top 4 brackets. Now I have all my brackets on and I've been doing rubber bands. I am satisfied with the straightness of my teeth but definitely not the alignment. it's horrrible and my bite is not good either. Right now I am wearing rubber bands. My orthodontist tells my I will probably get my braces off in late October of this year but I don't know if he even is going to be able to fix my midlines...
