What Could These Symptoms Mean?

I'm a 15 year old girl. Jan 2007, I walked into a Science lesson in school and felt increasingly unwell, to the extent I was sent home (I wasn't physically unwell and I haven't been). From that point onwards, I woke up every morning and felt unwell. It did become a little easier to deal with, over a gradual length of time. Then, around two months ago, I started to panic uncontrollably and it continued. It became stupid things, such as I was nervous about being nervous, petrified of the future and that my body was against me. It continued and still is. I have braces and have had them since December 16th 2007. I was fine with them and then last week, I began to panic about them making me feel unwell, physically. I return to school next week with Science first and I'm convinced I'll be physically unwell. I'm taking two Kalms tablets 3 times a day, having Psychotherapy/Counseling and I've had a blood test for the possibility I could be Anemic. What is this and how do I solve it properly?
