Kaylene, have you tried a rewards chart? This worked womders with my girls as mornings have always been hideous here! I did up a sheet for the girls which had pictures of what they needed to do in the mornings.
I.e. - 7am - get out of bed
Eat breakfast
brush teeth
get dressed for school
brush hair
pack lunch box into school bag
8am - leave for school

I found this worked really well for them as they kept checking their list to make sure all their "jobs" were done, and if they got everything done (without the tears) they got a sticker on their chart. When they got 10 stickers for getting ready with no tears, they got a reward (of their choice, pre agreed).

Now that they are 7, we still have a list (Chloe is forgetful and goes off into her own world in the mornings) and their jobs have just changed a little - they now have to make their beds and make sure they have everything for school like their library bags etc, and they can get dressed with no help.

A reward chart can be used for a short period to get them into the routine of getting ready for school. Once they have mastered it, you can wean them off the chart, or change the task - going to bed without tears, picking up of her toys etc.
