Thinking, are you in any kind of therapy or seeing a doctor for meds for your depression? I think if you went to the doctor that might make both you and your friend feel better that you were doing what you could to help take care of you. Not all anger from a friend or loved one is "negative" or about us, sometimes the other person is just unhappy and frustrated themselves because they can't figure out a way to help us. If you have trouble getting to the doctor, maybe your friend can help you get there and you can talk a little bit with her and explain.
