Thank you for posting the link to this site. It was definitely a light bulb moment for me.
I experienced non-epileptic seizures when I was a teenager and because Epilepsy wasn't diagnosed, it was treated as 'hysterical'; instead of receiving help for this problem, I was made to feel as though it was something I could control or stop happening at will. Not understanding what was happening or why and being blamed for it was traumatising in itself.
Thankfully I no longer have them, but the effects of how I was treated are still with me to this day.
