I am 17yrs old symptoms: pounding headache moodswings dizziness stiff neck/shoulder/back heavy head almost imposible to get my headup in the morning?

See your doctor. Although this could be viral; but the younger the age the more likely chance of bacterial infection. With stiff neck and not being able to get your headup i would worry about meningitis that can become dangerous. See your family md asap. If rapid decline go to nearest emergency room.
