I would probably pick her up and carry her home, is that weird? I mean if I couldn't wake her and there was no way to get help unless I left her, then I would probably take her home, and if I had a girlfriend in this scenario, my choice would not change.
I would take her home and place her in my bed, trying to be as gentle as possible, I would then check her fever and signs for any problems she might have, like if she was breathing I guess. I'm not sure if I would call an ambulance or anything, she might not want that, and I wouldn't act unless she seemed she was in critical condition or she asked me to call.
I would then nurse her back to health
and give her my cloths.
