Can you talk to your parents. I would start with my family doctor. I am no doctor but it is not usual for MS.
You probably should bring this to the attention of your parents, but what you are describing is not actually uncommon and it definitely doesn't mean there is something seriously wrong. Dizziness as you describe can be caused by many things eg flu, low blood sugar, a cold, and even poor sleeping habits, so speak to your parent's about what your are experiencing....
I mistyped I meant to say the symptoms are not usual for MS. You should not be scared by yourself. Talk to your folks or the family doctor.
