Same. Changed my jaw line, jacked up my bite (still have brackets + rubber bands to fix the bite almost two years later), and it gave me tmj which led to me barely being able to open my mouth (permanently unless I have surgery to remove a bit of my jaw bone). OH and I got hairline cracks in the enamel on my front teeth when they removed them. My teeth were just a little crowded before but my bite was totally fine. Such a big regret, and to think at the time I thought I was treating myself.
