Diabetic Seizures--Help!

Hi, my name's Becky and I'm seventeen years old. My best friend has diabetes, and I am very protective of her. We grew up together and I care for her very much. On one occassion, I was having a slumber party with my friend, and the next morning I awoke to her having a seizure. I was so scared, I had no idea what to do. I just cried and cried, thinking she was dying. Everything ended up okay, when her mom came in and gave her glucose, but now I'm absolutely traumatized. Whenever she sleeps over my house, or I sleep over hers, I never sleep PERIOD. I just lay down in constant fear. Whenever she rolls over in bed I wake her up in tears, thinking she's having another seizure. I don't think she knows how traumatizing it was for me to witness her having that seizure a few years back, but she does seem to get annoyed when I wake up her up several times throughout the night. It's been four years since "the incident" and even last weekend, I was laying next to her for FOUR hours when I finally had to leave the room because I would start to cry whenever she would move in the slightest. Because she's my best friend, she is coming on a vacation to Arizona with my parents and a few other friends of mine. I really want my friend to come, and all the plans have been made, but I know that they will be great days, and sleepless nights for me. How can I get over this ongoing fear of mine?? Please Help me.

okay...that sounds like a good idea. she has a pump (just to let you know) but what is a safe number that I could KNOW she'd be okay at? Also, what about the lowest safe number? Thanks a lot

Thanks a lot for your advice...the only problem is, I know the warning signs, and it seems as if I am always seeing them! We normally stay up so late at sleepovers that she gets crabby and tired, indications that she could be having low blood sugar. When she's sleeping, she always moves around and tosses and turns, which reminds me so much of her seizures, so i always wake her up thinking she is having an attack. So even when she might not be showing symptoms, i always think she is.

I want this all to go away.
