Wow, just wow, and so sorry to read about such a misdiagnosis. Are you currently under the care of a neurologist? When you had your first, pseudo seizure, your doctor didn't send you to a neurologist to rule out any physical issues, first and foremost.
Yes, angry, doesn't even describe, how I'd feel in your shoes!!!

{Edit to Add: Back in 2007, I had some strange, exhaustion issues, to just put this out there. I went to my GP. He noted on my chart, either psychomotor seizures or brain lesions. And immediately, his office set me up with a neurological appointment. Which led to my Multiple Sclerosis Diagnosis. Neuro, first, then Psych, because various neurological disorders, can and do, present as a psyche issue, when really, sometimes being ill, with a neurological illness, can present as something psychological. I cannot believe, my eyes, your story, yes, just, I am angry WITH/FOR you, right now}
