When the injuries you get from your seizures make simple things like brushing your hair or getting dressed intensely painful.
The summer before my senior year of high school, I had a grand mal seizure and ended up not only with a concussion and bad sunburn, but I had dislocated my shoulder. I couldn't lift it without being ready to scream.
Trying to put my shirt on hurt.
Trying to lift my arm so I could brush my hair hurt.
So I had to rely on my nan to help me do such things for the rest of the vacation, which very much sucked! :(
