Welcome to health care magic
I can understand your situation. I appreciate your effort to seek online support.
Ideally, in such cases, psychiatric help is of utmost importance for detailed evaluation as she is having suicidal tendencies.
There are various kinds of treatment available which includes drug treatment, psychotherapy/counselling
Try relaxing her with relaxation techniques
, deep breathing etc.
Make her busy talking to you on phone/skype etc.
You can also contact some NGOs to provide hospitalisation (if needed) and for adequate treatment.
Hope it helps
