My middle dd (15) has been suffering from some sort of depression/anxiety for a while. Nothing formally diagnosed yet, we have seen GP, she is on the waiting list for CAMHS and we are looking into seeing someone privately.
She often feels very down, dislikes herself, lots of tears and tantrums/meltdowns
Her behaviour and attitude to the rest of the family is awful and we are also suffering the effects. She can be rude and cheeky to both me and dh, and downright nasty to her younger sister. On Sunday we had yet another family day out spoilt by her refusal to shower and get ready, then had a tantrum because we were at the door waiting to go out. Followed by sulky behaviour in the restaurant.
The question is how to deal with it? I know she is feeling very fragile and I don't want to make her feel even worse about herself, but on the other hand I don't want to allow this sort of behaviour that impacts on others.
Any advice please?
