I don't think that you were wrong to expect your friend to be there for you, it sounds like a very poor reaction from her. It may be time to analyze your friendship with this person. Have you ever expressed any problems that you are having to her? If so how did she react to that? Is this a friendship in which she only depends on you to listen to her problems and she don't want you to share problems?
Some other things to consider is if she has any experience with depression?
It just sounds like something that needs some thought on your part, friendship is give and take and being there for each other.
I am sorry that she reacted the way she did, we are all here for you.
