Your mom is a big girl, and she knows she needs her meds. It isn't YOUR responsibility to give up your life because you are worried she may have seizures. I tell you this from experience. My kid has epilepsy, and she is responsible enough to take her meds without me telling her to, and she has been independent with this since before she was 12.
If your mom is having a hard time remembering to take her medication, you can help her out by making up a checklist she can use to ensure she remembers, and she can tape it to the mirror in her bathroom or wherever she is sure to see it on a regular basis.

Now get your bottom out of the house, and live your own life.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
