I am a graduate psych student and have my own issues as well. I'm not borderline but have some traits and have depression and some social anxiety. It's very common for people entering the field to have various psychiatric issues, but that doesn't exempt anyone from
behaving appropriately. Grad school is considered professional training and students are expected to behave accordingly. You will meet professors who are jerks, who don't communicate well, etc., just as you would in the workplace, and just like in the workplace, you
have to put up with it to some degree. I couldn't open your link so Im not sure of the details, but it sounds like you're not satisfied with his grading and communication style. This has
happened with me (I had a prof who never returned an assignment, so we never got any feedback) and probably happens to everyone in school at some point. Sometimes it's worth
speaking up in an appropriate manner and in the proper context. Much of the time however, you have to just accept that a professor often teaches the class the way they see fit. He is doing his job- you might not like the way he does it, but he is doing his job just the same. Your job as a student is to pass your classes and learn how to navigate and conduct yourself appropriately in the field you are entering. Badgering a professor because you don't like your grade will be seen by some people as harassment, and that will get you in trouble. The fact that you are borderline is not an excuse, nor are med side effects. They won't be in the professional world either and since you will be working with clients who are often vulnerable, this is an especially important lesson to learn. I would take this as a learning experience that might help you navigate these types of interactions in the future.
