Do the positions of brackets on the teeth matter?

From the first time I looked in the mirror after getting my brackets on at the ortho, I expressed my concerns about the position of my brackets. They are very low on my top teeth, and some middle, some high, on my bottom teeth. Dr says he did this cuz my teeth are long(they're not)and another time he said it's so he can incline them the way he wants. 2 months later, my chin and jaw are receding, my teeth are caving inwards, and my cheeks are sunken. (No extractions) but he did do ALOT of filing.
