i went to six flags last year and got on a roller coaster for the first time. and when it stated i was ok but as went on i was scared to death.
i can so relate to your experience! when i was a child my parents would try to coax me to ride and i hated it. i rode the ferris wheel once and started crying!
i went las summer and got on a roller coaster for the first time and it scared me to death i will never do it again.
