Should I message my old history teacher letting her know that I did not like

[Lee C]

what she did in the past? Or should I just let it go?I'm a 19 year old girl and I graduated a year ago from high school and I still remember about my history teacher back when I was a freshman. She used to treat me like I was stupid, probably because of the Spanish accent I had. But I'm very good at speaking English and I was back then. I also remember she asked me a question about my backpack but I did not understand her the first time, so she started laughing and she said to herself " She doesn't understand." There was a time when she was handing out papers to students to join honors classes and I wanted one. She then looked at me and said," You? You want to join honors, do you even know what honors mean?" That got me good. There was also a time when she was speaking to me about college and said, " I have concern in you, do you know what concern means?" And lastly, she was rude, one time she was walking in my direction and told me, " You're in my way." She also yelled at me one time in the library for something really stupid. She also got fired from her job later on, but I don't think it was because she yelled at me. I've taken 2 honors classes in 10th grade and passed them both. I've also taken 3 AP classes during my senior year and passed all 3. Right now I am currently studying business at college. She has made me feel so stupid but my family and friends say I am not. This has been bothering me for years, and I think I might feel better if I told her how I felt and I didn't like what she did, but in a nice through facebook. But also will I get in trouble at facebook? Should I say something to her?
