I'm sure he cares...He's probably just trying to take time to really read through and think about it. I think of my T who wasn't able to read and respond to my (fairly long) e-mail within 24 hours, and he said he felt bad but wanted to really take the time to think about it and respond (and I was paying him for it...). He responded the next day with a very thorough, caring response. To me it was worth the extra time. Your T may just need more time to process. I'm sure you're feeling vulnerable right now, so it makes sense to worry about whether or not he cares....
