I am so sorry, Emily, but at least you know what the treatment will be. Don't give up...
I can't speak to the jaw wiring part, but I had Invisalign braces from 2005-7. Yes, I had regular braces as a kid, but what they don't tell you, is that unless you wear a retainer forever, your mouth shifts back. I still wear the Invisalign retainer 3 times a week. The process was pretty non-invasive and moved much more quickly than anticipated.
Keep us posted.
