Dizziness problems

During the summer holidays last year, I was dizzy nearly every day. When I went out, I'd feel extremely sick and dizzy and I had to go home. But the bus rides made me worse and I ended up practically holding my head so that I didn't jolt around too much....

This continued for a while but then stopped. I then got the same problem back around October. I was at school when the room started to spin real fast and whenever I moved, I felt as if I was going to throw up. I had to go home. I went to the doctor and he said it was my hormones!!! I didn't believe him though, 'cause none of my friends have the same problem! He didn't think it was an ear infection, which my dad thought it was, because my balance was ok. He said something about the receptors in my neck as well... can't remember what though.
I think this might be inherited from my dad, as he's had and still has severe dizziness problems. Sometimes I still feel a bit dizzy, but I'm scared that the problem will come back even worse just like it has before!
What do you think it is?

I have a prob like this when I get a little bit of fluid in my ear....or my doctor calls it vertigo...you can take an over the counter med which really help me alot...and very quickly its called:Meclizine Hydrochoride 25mg but I only need o take half the tablet and I find releif in about 20 minutes. Same thing in the med Dramamine less drowsy formual I carry them in my purse cuz I never know when it may flair up...try it!
