Question by D.G: Help would be helpful... and very welcome. Dunno what's wrong with her?
My friend has been feeling ill a lot lately- she's 18, from the States (Unlike me, freezing my arse off in Canada) and asked me to check out some symptoms online for her (not necessarily yahoo, but hey.. here I am.). She hasn't been feeling at all good for around a week, give or take.
She fears that she's pregnant.
Or has cancer.
Or narcolepsy.
As you can see, this is causing her quite a bit of stress,

depression and anxiety scale
