Hi Rose, i hope your friend is recovering well and you are also able to focus enough on your own endeavours.
Your empathetic, practical support is wonderful

im happy the ideas may help, EFT is great. After such an ordeal is the time when deep seated limiting and destructive beliefs are often formed while trying to cope and make sense of it all and so all your support, healing and considerate words are helping to minimise it. Its also a time when one thinks and feels many awful things that cant be put into words or expressed for fear of reprimand/rejection by those willing to listen and comfort, so your reassurances and encouragement are helping to minimise it too.
It could help to remind your friend that being raped in a foreign country is too often a case of being a victim of cultural misperceptions and misread nuances on the part of the perpetrator, here in Africa (as in many other countries and cultures worldwide) there are often cultural beliefs, myths and gender role beliefs that are..... wrong or illogical

realizing that could help your friend to process her ordeal somewhat better.
The added trauma is the waiting for her to be declared HIV negative

(the added complication here in Africa) Louise Hay in her book Heal Your Body gives an affirmation/new thought pattern relevant to HIV perhaps you could make a laminated card and post these or similar words to your friend and suggest she read it every day or whenever she wants as an affirmation/prayer from you. It says..." I am part of the universal design. I am important and i am loved by life itself. I am powerful and capable. I love and appreciate all of myself." you dont have to tell her exactly what its for if you think it best not to and maybe you even want to say it in her name for her as a type of healing affirmation every day. Blessings to you and congrats on you upcoming move to Norway

Sending love, peace and healing to your friend
