Garnet...I really don't have any advice for you other than to remind you that it will be over with soon...and as long as you don't have to go anywhere, it should be ok...annoying as it is!
I think you're more upset over the loss of your friend, and the seeing her treasures going out with strangers than you are over the parking...I agree with reach 4 the stars...go somewhere in your house where you can't see the happenings out front...I would add...have a good cry, remind yourself that even tho they were her treasures that they really are "just things", and that the loss of her things won't take away the wonderful memories that you have of her.
