Sorry you're going through this rough time
I think the email you sent will be better address face to face than it would have been with email and that's probably one of the reson why he didn't wrote you back a ling email, especially when you're seeing him tomorrow.
I also think that he could have write anything but nothing would have really help you in the state of mind you are in.
And for the email, I know it's hard but I believe he was the best person to send it... there's stuff going on that needs to be address and now he knows about so that's fine; I'm sure you're not the first one neither the last to send those kind of email... I'm sure you'll make it through this and through the rough time you're having! You can always post here if you still need to vent!

I'll have a thought for you tomorrow for your session
take care
