Hi there... hoping to help you this evening... I am sorry that your daughter is experiencing such shock over this unfortunate discovery...
Extreme emotional shock such as what she is experiencing can be strong enough to affect the nervous system, which would be why her extremities are going numb and feeling cold... and your support is very important to her right now. Trying to explain to her that her body is just reacting to the news physically will help her to stay calmer and not end up feeling anxious about her health.
If you have serious concerns about her, your family Dr. may be able to prescribe a sedative or something to help her body to regain balance. Generally, initial shock can be numbing which is helpful to keep the body level while the mind deals with the reality... but in her case, she is reacting physically first...
This is clearly her first time dealing with something so shocking and serious; she needs guidance and your calm leadership to teach her how to stay calm in the face of circumstances outside of her control. Just comfort her, let her grieve this loss... and reassure her that you are there for her.
The poor girl! :-(
I am here to help and support you, and want to give you whatever information I can to reassure you; Do you need any further information or have further concerns or questions that I can help you with?

thank you for your help - if it gets worse I'll be back
Encourage her to focus on breathing slowly and to stay in the moment and not think too far ahead. She has every right to be angry with him, and remind her that she has done nothing to deserve this happening to her... my very best to you, and to her!
