My 14 yr old daughter began to self harm, over dosing and cutting, in April after her father suddenly and unexpectedly left us to move in with his affair relationship who was a family friend. My girl, who was a high achieving and academic girl has completely fallen apart and is cutting and taking any over dose she can get her hands on. I am at the stage of not knowing how to cope with this. She has began to cut if I try to impose any boundaries which is really frightening me. Any advice welcome please.
