I kind of disagree that they aren't paid to care. Why do people get into a position working with young adults in a very stressful time of their lives if they DON'T care?! That drives me insane.

If it is social anxiety and the size of classes that are the issue, is it possible for you to have a tutor? That way it can be one-on-one? You would still have to go to class but, at least that way, if you are distracted by your anxiety during class you can still catch up in a calmer environment. Have you spoken to your parents about this?
