Malabsorption, malnutrition. At my sickest I was down to 105lbs. (my norm is 120ish) For the life of me, no matter what I ate I couldn't put on weight. I was extremely exhausted and weak, and had 2-3 seizures that summer. I thank god everyday Kyle was living with me at the time. He literally caught me and saved me from falling and smashing my head on the desk in our bedroom, mid-seizure and just held me until it stopped. Scariest ever. I'll never forget that.
