Im a therian and I mental shift in public with my family around help?

[?The End Is Near™?]

Whenever I go out with my family,say we go to town or something,I mental shift (look it up under 'therianthropy'.).Im a horned owl therian and it's quite hard around my mum and dad as they don't know about it.Mental shifts come out of knowhere for me,I don't know when to expect them at all and I don't know how to stop them.I get the urge to do 'things' aswell .

Please before answering do some research if you havent a clue what im talking about.Any immature or inappropriate answers will be deleted.
