I need help with this neck problem?

About 2 months ago, I woke up for school on a Monday morning while sleeping on my stomach and, having my head rested so the right side of my face was on the pillow. ( I was looking to the left) I then turned my head/ neck to get up from bed, and felt an awful pain on the left side of my neck, kind of in the vicinity behind my left ear. I went to the doctor and they seemed absolutley certain that I had a torn facet joint. They prescribed me to a chiropractor and said it will take between 4-8 treatments of neck adjustment, and I'll be back to normal. I have went to the chiro 10 times, and have now canceled any more visits as I find my neck is now worse. It feels stiff, sore and cracks a lot. It is interupting me with everything I do in the day. I have trouble sleeping now ( abd yes I got a new expensive support pillow for my neck) It feels like a wall on the back/left side of my neck when I get out of bed in the morning and even throughout the day. I constantly have the feeling of needing to crack my neck, and even without using my hands and just tilting my neck to the left, my neck is cracking. I'm going back to see my doctor this Saturday. Do you know what can help me? Or do you know what's wrong with my neck? By the way, I'm 16 years old, and before I started going to the chiro my neck never cracked yet when I supposivly pulled this joint in my neck, it was very sore and stiff.
