I hate being abandoned, and when Angels in Manhattan came out, I was in a very dark place emotionally. Seeing River leave the Doctor at his biggest time of need made me angry, largely because it hit so close to home. I needed support from friends, and no one really gave a damn enough to help.

The only reason I am any better now is that I have essentially given up on not being lonely, and have just became cold bitter after damn near everyone leaving, and the remaining ones being unable to help in any huge way. People suck. End of story.
