Stand up and start shaking uncontrollably, dizzy, can't talk but i can see the things around me, lasts a few seconds. had this for years?

Tell your doctor: This may be orthostatic hypotension. Your post is puzzling. If you've had this "for years," why didn't you or your mother tell your pediatrician? If you're concerned enough to post about it, surely you were concerned enough to ask? You've aged out of pediatrics, so you need a primary care provider. There's a simple test for OH that can be done in a doctor's office in <5 minutes.
