Hello, I am a 16 year old female I'm 5'2 and 96 lbs. Within the last month I have lost 15 lbs. I've also noticed that I've been feeling sick and sluggish about the same time. Its worse in the mornings. But anyway, I'm the last 4 days I've had a severe headache like pounding. I have had dizziness impaired vision and actually fainted. There's a tightness in my chest and I'm short on breath. There's a sharp shooting pain the back of my neck also. There's pressure in both ears and it hurts when I breathe. I don't know what to do.
