sleep disorder

hello my name is Stacey-Jane and i am 17 years old. Unfortunately i have had these particular symptoms for around 2 years now and the hospital have tried to help however, there is nothing for them to do as every test has come back all clear and normal. My symptoms is my chest will become tight and i will get a pain in my chest, however this doesnt occur every time. Suddenly i will then become weak and drozey, which then means that my whole body becomes like jelly and find it hard to have the energy to do anything. after this, i will then find it a struggle to breathe normally and it becomes loud and unusual. i then have pins and needles in my hands, arms, legs and feet. my hands will then become stiff. i then fall into a sleep mode and could be out from 20-45 minutes. while this is happening i can hear most things that are going on however i dont have the energy to reply. i have been told that while i am asleep my eyes will flicker, my hands will twitch and go cold, anyone around with me will then find it hard to move me as i am just a dead weight and find it hard to move me. However, it comes out all different as i have vomited before and it was only my eyes that flickered and then went asleep.
i have then had many tests and all come back as norm, im worried for my own safety and others because i have to travel everyday on my own. could you please help me as the doctors dont know.

This almost sounds like a sort of seizure.  Has anyone tested you for this?
