Behavioral problems

I posted this once, but received no responses. I changed the title so maybe someone will take an interest! Here is a brief history of my three children -- what do they need? Please help!

Shayne, 11 1/2
Has ADD, cannot concentrate, difficult to stay on task, gets B's and C's in school, does have a family history of cancer, does have a significant amount of moles on his body, rather quiet--doesn't like to have lengthy conversations, forgets to follow through with simple tasks, has mild dyslexia with simple words and numbers, suffers insomnia, sometimes has migraines

Trystan, 9 1/2
She easily gets her feelings hurt, I think she might have ADD to a small degree, tends to stay in her room alot, complains frequently of pains in her stomach or legs

Troy, almost 7
Every definition of ADHD, scared to be left alone, afraid of dying, very mean to girls -- especially his sister, cusses when really mad, very safety conscious, bounces off the walls, spoke his first word days after he turned two, dyslexic, very affectionate to mom -- no one else.

Please help me help them! Thanks!
