I know how you feel! *hugs*
It's no where near as bad as losing a pet-but I had a very large stuffed rabbit that a family friend won for me when I went to the circus. This was when I was 4 years old and I;m ow nearly 19. My mom decided to tell me JUST before I had to take an aptitude test for a job that she'd thrown him in the bin. ;_;
I hated myself for not paying attention to the rabbit until it had gone.

Believe me, my plushies mean a lot more to me than you think...
