Please help. i am getting afraid?!

Please help. i am getting afraid?

i was at an amusment park last weekend and the first ride that we went on was wicked. It was a rollercoaster and it went frontwards and then backwards. i did well backwards and it was a lot of fun, but when it switched to go frontwords i remember screaming and then i blacked out. when i opened my eyes i was trying to keep my head up, but was unable to.. i was acting like i was going to passout. when the ride stopped, i wasnt sick, i wasnt dizzy.. i was fine. i was fine the rest of the day but i am scared to go on rides now. I am a HUGE fan of amusement park rides and went on a lot of them before. A big contributing factor that may be helpful is, everytime i am on a rollercoaster and we go really fast and then incline or something i lose site for a few seconds.. and feel fine. IS any of this at ALL normal? i need to know, because rollercoasters are so much fun and i want to continue riding them

I would say stay off the rides, that does not sound at or normal, or safe. At least stay of the rides until you get the opinion from someone like your doctor. Ask your doctor for advice, it may be normal and there may be a perfectly fine reason for that, but I don't think there will be... so be careful and stay safe... Ask your doctor.
