I don't know what she's feeling or if this is in any way helpful. But for me I can't stand people trying to fix me or help me if I don't ask first. When I do ask it is for that moment. You can try asking her if she wants you to help or if she would rather you just be an accepting support letting her experience what she needs to experence. Empathy is not easy, it means trusting the hurt person to let you know when they need you. Of course if she becomes an immediate threat to herself or other you need to call a professional, don't try to handle that on your own.
