Well for me i used to get all lighthead for about 2 minutes then it would stop and that would be it. Now its constantly happening in splooges over the day. Usually during after school. The most common times it would happen is at night out in the public instead of being inside the house just relaxing. So far its only gotten to the extreme once where i wouldnt be able to stay at work and i had to go home early. The only tests iv'e had for this so far is blood sugar (cause my mums diabetic) and eye test. Both fine. I've learnt that keeping myself occupied (school is a great example) keeps it from happening. I guess when i grow the bullocks im gonna get more tests done. I've been doing a bit of research and i think i may have anxiety. And it might be true because i often don't like socialising under my own free will e.g partys, get togethers..etc. Anyways the point of this post is just to see if anyone has any knowledge for your illness you have. I'm only 14 btw
