The illness does.

Your son sounds exactly like me. It may not be the case for him, but I often stay up all night when I'm down, because if I go to bed, I won't sleep, I will lay there thinking worse and worse thoughts and feeling worse and worse.

In the end, I get tired, so I end up being able to sleep- during the day.

When I'm down, it's a miracle worker who can get me out of bed sometimes. I just do not want to move.. especially not for a hospital appointment, they are stressful! It really doesn't surprise me that he doesn't care, I wouldn't either, because all I would want is my bed.

It is crappy, it's very crappy. But do your best not to get frustrated, as understandable as that reaction is. It won't help him feel like he can open up to you. You need to communicate.. he needs to know your feelings and vice versa. But that is much easier said than done.
