Tonic Clinic Status seizures

My daughter in law has epilepsy and has had seizures from the time she was 14. She told me she had a couple different types but not sure right now. She doesn't have insurance at present but she does get her medicine that is still prescribed to her. Two days ago her husband was in a hospital for acute pancreatitis. I stayed at hospital because I can't drive in the dark. I went home the next morning and DIL was in my bed and did not know me. She was frightened. She was crunching on something, later found out it was part of a tooth. She was spitting and was soaked PJ's, bed etc with urine, she was flails, but moderately. It tums out she had gone into a seizure shortly after we left the night before, probably around 9:00. I found her about 8 am. So possibly 11 hours in house by herself having a seizure. Well, actually longer because I didn't know how long she had had the seizure. I tried to stroke her hair and talk softly to her and she would look at me and recoil and try to get away but she couldn't talk except the moaning and grunting and spitting. But after 30 minutes I was too scared not to call ambulance. So they came and took her to hospital. They gave her a couple Ativan shots and she seemed to relax a bit. But she was out of it for almost 24 more hours before she started talking. They did an EEG and MRI. She said they were abnormal but that was to be expected after that. (Oh, when she was seizing she would also rock backward and forward. ) I noticed her ankles were swollen. She said that's part of it. Not sure about that. My son has always been with her when she had seizures. Not sure if him not being there had a contributing effect. She had received distressing news the night before. I know nothing about all this. She said she had tonic clonic status seizures. It seemed like a very concerning event. I would appreciate any input.
