Terrified of roller coasters..helppppp?

hey you're the same age as me! so anyway my older sister (16 now) is still afraid of rollercoasters,. A few years ago she went on the Rock n Roll rollercoaster in disney while being afraid, yet she still thought it was great. however, she hasnt gone on one since. I greatly encourage you to start because, unlike my sister, you will get used to the strange feeling and start to maybe like it! you have to try to know so i strongly urge you to go on one just to see. perhaps you might start on one less crazy lol because then if you get scared of the larger ones, you'll never go on one again :(
