Glad you are feeling better MM. I'm not a parent but I would guess that are a lot of parents with similar worries. I know one of my cousin's children had to be forced to learn to drive before college.

Is he online because of COVID or by choice? If by choice maybe next semester he can try an in-person class and just slowly get into it. Maybe he'll click with a professor or make a friend in the online group and that might help him.
