You know what? You advocate for your child. You search for answers. The love for your child is obvious in your words. You are a wonderful mother.
It's hard not to second-guess ourselves. Lord knows I do it ALL the time. When those we love and trust second-guess us, it makes it harder. When your difficult child is being mean and hateful, it hurts and wears you down. You do eventually develop a thick skin. My difficult child told me tonight that she hates me. My only reaction was surprise that she didn't say, "Why do you hate me?!!?"...her typical response to anything that doesn't go her way. LOL It used to rip my heart out, though.
