I'm not a parent (yet), but I've certainly have been a child. And I don't know where would I be right now if my parents hadn't thought me how okay it is to seek for help if you need it. I've gone to different therapists, psychologists and psychiatrists through the years and it has certainly made me understand things better. Sometimes there's only so much you can do before asking others for help. Maybe you and your daughter need that help. Either way, I hope things get better for you as a family!
