So basically my Psychology class will be entering a unit on mental disorders and I am not excited about it at all. I always feel iffy talking my own mental illness without going into a deep plunge of sadness right after, and having to be a classroom with a bunch of people who have little to no understanding means chances of them saying hurtful things is sky high (I assume, hope I'm wrong) 

Should I talk to my lecturer on other alternatives, like for my syllabus we get to choose between a few different topics like mental disorders, consumer behavior, etc. etc. ?

I just don't want to have a mental breakdown or get overemotional in front of my coursemates....
