Dont know if I have epilepsy

Hi I joined this website to find out what somone thinks of what I feel like who has actually been dignosed with epilepsy. I have had three funny turns as I call them, the second time I went to the doctor and explained what had happened and he was really not alot of use. What happens is, It feels as If somone has got hold of my head and shoke it quickly forward and back, then I go complety dizzy feel really odd,I am aware of my husband talking to me but I don't feel like Im there with him, I feel sick, have to sit with my head back agaist the sofa untill the spinning stops, I always cry after as It scare me, I then feel really heavy and drained and go to bed, the next day I feel do odd and not with it and friends have said that I look really spaced out.The last one happened whilst on the computer. One friend thinks it's a sezuire but wouldn't the doctor thought of that? I don't know what to do, can anyone tell me if they think it could be epilepsy or totally not?I just would like advice from somone who knows. Many Thanks xx
