To be honest, I am not quite sure why you're posting this question on a Tamagotchi forum... ^_^
Think about it for a moment.
If you really have the symptoms you describe, and they've been happening for about 2-3 months, then your parents or guardians would have already taken you to the doctors or the hospital for a diagnosis...
If your parents have never seen these seizures or episodes (even the ones that last 5 mins) that shouldn't stop you describing them to an adult and seeking medical attention ... (
unless of course, it's a different kind of attention you are seeking - in which case you need to check the site rules on Banned Topics and Posts: https://www.tamatalk.com/IB/index.php?showtopic=92971 )...
I'm really sorry, but no one on TamaTalk is going to be able to help tell you what is wrong with those kind of symptoms
that's really a job for a doctor...
