My daughter has always been no trouble, good girl, works hard. Has just discovered going out and socialising with friends. She has just tested positive for covid but is refusing to self isolate. She said she has had it already (all LFD's come up negative but PCR is positive) although she has never had a positive test before. I have begged her to stay in and she has just walked out. I am beside myself and don't know how to deal with it.
