<s>[INST] Hi my question is that my girlfriend isn t feeling very well, we just went bowling and she felt like she was about to faint,dizziness, and also she feels like she s hot in the inside but cold on the outside. This also isn t the first time this happened two weeks ago she fainted from the same symptoms. I was wondering what it could be.
