Autism & Xmas

Xmas was ruined by our 26-year old autistic daughter's outbursts. We did all we could to minimise changes to her routine but they kicked off on Xmas Eve & reached a peak late Saturday afternoon with one lasting nearly an hour. Total 8 in 24 hours. We still don't know what drives them & triggers are unclear & inconsistent despite exhaustive psychological approaches being used. She's spent a year in hospital now & I feel as though we're no closer to stabilising her. If only she could tell us what she's feeling/thinking :(
