F for FAILURE...here right now with my 18 year old daughter who has Rett syndrome. We have been here for 3 hours spoke to 5 different people who all asked the same questions and said they would be back w a med to make her calm...i had her calm , almost sleep and what do you know someone else knocks on the door (i thought it was the med coming) and said the same exact ish...now she is back up and more upset ...
