Hi . According to the evaluation on the basis of your symptom profile it appear you had complex partial seizure
. As you were on valproate
which is an antiepilectic , you did not have seizure previously. But when you stopped it sometime back , you had that episode. Secondly there are chances that you had a dissociative episode as you had been diagnosed with borderline personality also. So all you need is , consult the psychiatrist
, get your appropriate diagnosis and start treatment. Seizure have a bad thing that, one seizure increase the propensity for second seizure . Thus treatment should be started ASAP.
