That is great you could get even two weeks away!, it could be many things and by talking to a doctor about what is going on with her and the doctor doing some tests like MRIs and EGGs what might be wrong can be found pretty quick! Maybe it is something else though that does not show up on a test or with a Medical doctor. Maybe she after that might want to be referred to a Psychologist or something. For now keep an eye on her and support her! Good luck to you both and God bless!
