Thank you all for your advice and support.
I was away during the day, and my in laws stopped by while I was out. Last night I think he was having a seizure, but this afternoon when I got home he was having a really bad seizure. I called EMT's and they just picked him up. I decided that I can't emotionally handle going back to the hospital with him again.
Gosh, I wish Monday was already here (my meeting day).
