Oh God...

Doctor Who is on today at 6:40pm. I feel sick. Hopefully there will be a trailer for Series Five afterwards, but that still doesn't take away from the fact we're saying goodbye to the Tenth Doctor.

There's so much I'm not looking forward to. How will he regenerate? Will Wilf survive? And what about Donna? How will the Doctor defeat the Time Lords, and the Master? How much will we see of Matt Smith? I can't take anymore... I need to see it now!!
