I am at my wits end. My daughter is a lovely girl most of the time. Very loving, caring and selfless. Right now she is doing everything she can to assert some authority and push my buttons. I find myself screaming at her or breaking down in floods of tears. Only last week I took away her devices and this seemed to work but what other tactics can I use? I am going to sit her down and try to talk it through and see what her take is on what's happening. She went into school in floods of tears this morning after starting and continuing a stupid argument over nothing. Please help :( I want her to feel loved and supported but at the moment I am struggling to even look at her.
