"Mommy, you broke my heart!"

That's what Ariane has been yelling out her bedroom door for the last few minutes. And the reason she's so upset is because she is grounded to her bedroom all weekend long. No TV, no books, no friends, no pillows or blankets during the day, nothing! She has to sit on her bed and think about why she's in there. I am tired of fighting her to take her medicine. She has wasted 4 pills just this week! I sent her to school without being medicated. I also sent a note to the teacher stating that if she had any problems with her, to call my cell phone right away and I would come deal with her. I am at my wits end with this child. I no longer know if I can handle her moodiness and petulance without cracking. Please someone tell me that it is going to get better! I need some reassurance that I'm not losing my mind!
