This must have been very upsetting. I have a son who is 14yo who has epilepsy. Even though I have been a pediatric nurse for over 30 years and have seen literally hundreds of children have seizures, I never get used to seeing my son seize. It takes my breath away.
Now, there are a lot of things that will cause a young lady to pass out--dehydration, severe menstrual cramps, and stress can do it. There are some more serious things that can cause fainting and can look like seizures--sometimes they are real seizures and sometimes they are something else. I'm sure your friend's mother will talk to her doctor about it and hopefully, have her evaluated.
My oldest son, DS23, had a similar episode when he was a senior in HS. One day in Lit. he just shot out of his chair and fell to the floor unconcious having a seizure. It terrified the whole class. When he came to he didn't know what happened and didn't recognize the teacher. I had the school call 911. At the hospital they gave him IV fluids and ran some heart tests to make sure he hadn't had some funky heart rhythm. A pediatric cardiologist(heart specialist) came to the ER to personally check him out--thankfully, his heart was fine. He finally perked up and starting joking about 2 hours later so they let him go home. The next day we took him to a neurologist to test him for seizures--again, the EEG and MRI were normal. What a relief! Anyway, they finally decided that he had probably had some kind of random seizure, but that it didn't seem likely that it would happen again since nothing checked out badly. And that was it. He has never had another one.
I hope your friend also has a good outcome. Maybe you can talk to her in a few days and let her know you care. She might be a bit embarrassed,so don't take it personally if she doesn't want to talk about it. But she'll know you're thinking about her and she might feel like talking at a later time.
