My wife just had her fist seizure at 31

Yesterday morning I was awoken to the sound of my wife yelling my name in our hallway. I hopped out of bed and was able to get out of our bedroom and find her still standing in our hallway with her upper extremities decorticate posturing, head turning left with jaw spasms and grab her and bring her safely to the ground. I am recent graduate of CRNA school and had worked for 5 1/2 years in the ICU prior and had witnessed many seizures during my time, but nothing I have seen prepared me for the moment I witnessed this happening to spouse. As I grabbed her my medical thoughts immediately went to 31 year old, healthy female, has been on birth control, she is having a stroke. As I laid her down she entered the clonic phase and began to convulse with dilated pupils and kicking the wall. I pulled her over to the middle of the hall way to get her away from the wall and rolled her on her side. I noticed she was "foaming" at the mouth and thought about shoving a towel in between her teeth before I remembered my training not to do so. I stayed at her side throughout the violent shaking until she stopped and started having agonal breathing and turning blue. I gave a jaw thrust to her at this point and noticed she spit out some blood and was just praying she did not bite her tongue in half. After she started breathing regularly I ran and grabbed my phone and dialed 911. I gave our information to the operator and stayed by her side attempting to call her name and shake her every 15 seconds or so until she started to respond. The "tonic" phase appeared to last 15-30 seconds and the clonic phase roughly 2 minutes (though it felt like hours), and she started to respond to me after about 5 minutes. The paramedics arrived within 15 minutes and by that time my wife was awake answering questions, however she did not remember when the paramedics initially arrived. She was able to wake down to the ambulance with them and was taken to the ED for further testing - CT scan and labs were all negative including pregnancy and thyroid testing. We are currently scheduled to have an EEG and MRI this Tuesday. This was my wife's first seizure and she has no family history of seizures. My wife is extremely healthy - works out 5'3 120 pounds and works out 5-7 days a week. She does have a history of anxiety and depression and had been switched to Buproprion (Wellbutrin) about 2 months ago, the same time we had stopped birth control). Her only other medication is a prenatal vitamin. Both of us have been very hyper alert to the possibility of another episode like this happening since. We discussed with her physician and stopped buproprion and switched to Zoloft for her depression/anxiety after the episode. My wife did say that her left hand started going numb (like she had sat on it and it fell asleep) and then her left arm started contracting before she starting heading down the hallway yelling for me - which she remembers, about 10 seconds before she lost consciousness, which upon researching sounds like a a focal to tonic-clonic seizure. We are both concerned about how everything will play out with this will play out and are curious if anyone else has experienced anything similar to this. Thank you.
