Hello, I hope you are very well.  
I'm not really sure how to start telling this, because, in a way, I feel a bit ashamed about how much I've been affected by a situation that I feel I shouldn't be (at least not to the extent that I was).  
As part of the elective courses I can take in college, I decided to take a course on leadership. I am 23 years old and during my college life I have been a part of several organizations where I was able to assume certain leadership roles, so I was very excited to take this course (especially since it had been recommended to me by many).  
I take my classes every Friday and the dynamics of the course are quite strange, I feel that sometimes, under the concept of the course we are forced to put ourselves in situations of uncomfortable silences to take the initiative.  
A few days ago something similar happened and we were told that we had a few minutes free in which we could do whatever we wanted. I tried to take the initiative and asked if in that free time we could do an ice-breaker dynamic (if the time they were giving us was ok for something like that or if it had another purpose) and the teacher completely misunderstood what I said and started to accuse me of being authoritarian because I was waiting for her "permission" to do what I wanted and that since I lacked authority and leadership in front of the others, nobody would want to do something I proposed.  
It is important to emphasize that everything she said to me said it in a despotic way and front of the whole class (class by zoom, all with the cameras on). When I heard what she said to me I really felt ashamed because of the public humiliation, and everything would have been "fine" if it wasn't for the fact that while the rest participated, she kept comparing me with the rest ( taking me as an example of how a good leader should not act) and kept throwing hints at me.  
I am a very sensitive person, and when we had our break, I couldn't help but cry a little, I had never felt so humiliated in my college life. When we returned to class I started to feel as if I had lost the respect of the rest, because when the teacher asked questions about what we had learned today, one of my classmates made an example of me about how "to mobilize people, I must first be a leader". I think the latter was what hurt me the most because I know and feel that I am not a good leader, but I had never seen myself as an authoritarian person or a person with bad intentions, I feel that I have been unfairly interpreted and it hurts me to think that no matter how hard I try to be the best version of me, I do not achieve it, that makes me feel very frustrated because I feel as if I were a lost cause.  
When I was 15 years old I suffered from such severe depression that I almost took my own life. I remember how I cried every night and it was very painful for me to feel so bad that day that I couldn't sleep either. I am very afraid to think that my mental health is so fragile that I depend on a single mistreatment to collapse.  
For a moment I thought I had taken it too personally and I asked my friends if the way I heard it and the tone in which she spoke to me was the way I felt and indeed, they also told me that they were "shocked" by the way the teacher treated me.  
Sadly, talking back to the teacher or complaining to the university are options that I have ruled out because I am on a scholarship and can't afford to let the teacher take "revenge" on my grades.  
The good news is that I only have three classes left, and I wanted to ask for your advice on how I might deal with these next classes:

1. Should I keep quiet and not participate at all so that she doesn't take revenge on some comment of mine (this is the option I am considering the most as I no longer feel comfortable in that class).
2. Should I continue to participate and play loud music when she wants to tell me something?
3. Is it normal for such an act to trigger the crisis I felt? (well, I think the obvious answer here is no).
4. Is what I feel really valid, or am I taking it all too personally?

Thank you very much for having made it this far, I want to apologize for the English since it is my second language, I hope you have a great day :)
