For one thing, one person can't cause another person's depression. It probably made her feel bad when you said that. We are responsible for our own moods and we cannot blame another person for the way that we are feeling.
I would do as posted above and call her or try to talk to her and explain that you still want to be friends. Maybe you didn't mean what you said. Or maybe it did come out wrong. But to try not to blame your friend for your depression. I hope that the two of you make up and become friends again.
