I have noticed a huge upswing in numbers of students with 'anxiety' as their disability at university, the past two years in particular.
I'm supportive of students with depression and anxiety and have worked with lots of students to make sure their mental health issues don't overwhelm them and they are able to graduate.
My only worry is that it is becoming a reason not to do things, to the extent I am concerned they are missing out on skills and participation- so for example, they are allowed not to attend class (which normally they would), not be asked direct questions in class, only do presentations to staff and not to the whole group and so on. On the one hand this is good in that it keeps people with severe disorders participating as much as possible and circumvents some of their worst fears. On the other hand, going into a workplace with little or no experience of speaking in groups, or doing presentations feels like a failure on the part of their university when we are supposed to be encouraging these skills.
It is not one or two students per cohort, it's several students per class. It also makes it hard to run seminars as you can't ask anyone anything (unless you can remember who is the person you aren't supposed to ask anything, but there's too many now to remember that in large classes).
All in all, it does seem like an epidemic of this particular issue right now, for a reason I'm not sure of. I don't doubt, by the way, that the students are very anxious, and have mental health difficulties- I just feel sad that there are such large numbers of them now, and also concerned whether our response should be 'just don't participate then' although I know many actually battle on even though they feel awful.
