names

So I go by two names, and the one I use online is Bobby because nobody calls me it in real life. Anyway, I've been writing my other name and /Bobby on all of my school papers, and anywhere I need to sign my name. Somehow, my Exploring Apparel and Interior Design teacher didn't realize this, and she called the name Bobby out because we had to put our names on a google form and she didn't recognize it. Mind you, I wrote my name like this:

*Other name*/Bobby

My other name that everybody calls me WAS IN FRONT. IT WAS THE FIRST THING YOU COULD READ, SO PEOPLE SHOULD KNOW THAT IT'S JUST ME. But my stupid teacher called out the other name and was like "Who's Bobby?" and looked around. I tried to make eye contact with her and I mouthed "Stop" to her, because I was becoming more and more embarrassed. She then pointed at me and said, "Don't put made-up names on google forms." 
By then, everybody was laughing. People were making fun of the name Bobby, and were like "LMAO WHOSE NAME IS THAT IT'S SO STUPID??!?!?" 

After being fucking humiliated and getting no apology from the teacher, I walked up to her and told her she was being transphobic after class, and she just kind of looked at me like I was crazy and hesitantly apologized. So that was lovely.
