Just woke up from a nap to some horrible news. My sister got a call from our dad's boss who happens to also be his good friend and he had to call an ambulance for my dad because it appears he had a stroke. My dad is completely disoriented and completely unable to talk. I don't know how to feel or what to do, just went completely numb
