Hello and thank you for your question.
It sounds like you are being supportive of her and are basically just looking out for her best interest. The symptoms you describe do sound like depression and I agree with you that she should be seen by her doctor. You made the right call there to get her help now, sooner rather than later. Even though she is angry with you and left to cool down, the anger could be just another sign of her mood/depression, or it could be about the recent stressors, etc. Regardless, one thing is certain is that she does need to see her physician (it's good that you are going with her) and it was the right thing for you to suggest. Don't second guess yourself about that one. I would wait and see what the doctor says today, before you decide on talking with her parents. The doctor might suggest an antidepressant and/or therapy and if you see an improvement, then of course, it may not be necessary to tell her parents. I would really wait and see what happens after the appointment, what the doctor advises, and how she progresses from here. If you would like to give me your zip code I can send you a list of therapists in your area who treat depression. You can also ask the doctor for any referrals as well.
Once she is feeling better, she may not be angry anymore and if she still is angry, then at that point you can address any issues in the relationship. But for now, the depression really is what needs to be addressed.
