Refuse going to day care

It is the 8th of my daughter going to the day care and she still doesn't get used to it. She cried every morning when we drop her at the school. Today she doesn't even want to get into the car. Contradictory to what i thought it should be, the situation has become worsen. I really feel stressed each morning when I need to sent her to the day care. But i know that I can't give in. Others keep telling me that this is normal and depending on child, some may take one month to get used to it. I understand this but it was just hard for me seeing her crying, screaming for mommy and holding on me tightly. :(
If you have any tips how can I handle this situation better, do feel free to put your comments, thanks.
