Lots of us do, but they are like that for different reasons. Has she ever been evaluated? How is her development? Is it on time? Did she walk/talk on schedule? Can she communicate well? Is she sensitive to food, fabric, light, sound? Do you have any mood disorders or substance abuse on the family tree on either side?
My son used to throw his time out chair at us if we put him in it. He's doing really well now at 14, but we had rough going at first. He didn't sleep for the first two years we adopted him. In fact, he'd walk right out the front door at night so we had to make sure we had locks he couldn't control. At her age, in my opinion, the best you can do, diagnosis and intervention-wise (and it probably won't be 100% accurate) is to take her to a team of experts called a Multi-Disciplinary Evaulation. They do them at university and children's hospitals, and they can at least point you to areas that may be causing her behaviors. If she needs extra help, they will tell you where to go. My son had two of these--and they never did get his core problem 100% right, but they were able to pick up trouble spots and get him help in school, which he desperately needed. I don't think he'd be doing so well today without his early interventions. You may also want to contact a developmental pediatrician, but at age four, I'd go with the MDE first. Either that or a neuropsychologist, who basically does all the work that the MDE does.
