Just keep telling yourself it's only a few more days! I haven't read much spec myself, but I found that posting some helped deal with my post episode freakout.

I actually feeling rather zen about the finale right now. David Tennant is NOT leaving (no spoilers so don't tell me he is). Rose HASN"T moved on and decided that the Doctor was a youthful experimentation. And now I that know Donna is PIE I know what happens to her - she gets unmasked and then everyone gets hungry after defeating the Daleks.
