That's another thing that I had thought about, but I also know that every time I had witnessed her taking her medication, it was done in front of whoever was giving it to her. They would bring her the pills and a glass of water. The girl is almost 20, but has the mentality of a third grader. She is well aware of her condition and every time that I have spoken with her, she has made comments about looking forward to her seizures stopping for good.
That really makes me doubt that she is doing this to herself.
