I am totally at my wits end my nearly 18 year old has serious self esteem issues , is constantly lying and has been violent to me . she creates constant drama , is social media obsessed and never manages to keep friends . She threatens to leave and despite good grades and very talented she only wants to be popular . we have paid for counselling, private education, we tell her we love her . She can flip really easily . Our younger daughter is totally different. I have no found she is posting on a sugar daddy : findom site . I haven't told my dh because he will not cope . I feel I am drowning . What do I do ? Confront her ? Please help
