Hello Gabriel -- You did absolutely the right thing, and it took a lot of courage -- really a lot -- to help your friend.

I can imagine how you feel because of the way she looked at you; anyone who has ever owned a pet knows how a look can tear your heart out (even if all one is doing is refusing to let the pet glut itself) . . . but you must keep in mind that her feelings are very distorted right now. She is not thinking clearly. Perhaps it will take a long time, but hopefully she will stabilize and know that you have been the very, very best of friends and hero -- not a traitor at all.
