Take small steps toward your goal. Find out what rides you can take — what type of rides don't bother you and what rides make you nervous just watching them.
Ride a small roller coaster that you are a little nervous about. It will usually only last a few seconds.
Progress, slowly, into bigger or faster roller coasters like the one in the picture. (Joker's Jinx at Six Flags America)
Go with your boyfriend who knows your situation, yet will be able to encourage you and give you confidence in getting on to the ride.
Big and Bad! When you find your limit, don't ride anything bigger unless you are ready to push your limits. It doesn't matter what everyone thinks of you; you found your comfort zone. Don't let anybody try to push you around or pressure you into riding rides you aren't comfortable with yet
If you're going on a loop, just look down at the ground of the seat. You'll feel like you're just going straight; keep your head against the cushion, though.
If it is your first time on a pretty scary one, don't sit at the front. This is because you can see what's going on, even if you look away.
If you don't like the coaster you're on, and it's way too scary, just close your eyes, you'll be fine. Just think of it as fun and don't use your imagination too much because it will scare you. You know that you are going to live and you will eventually get off the ride safe as long as you follow the rules. For some people, however, closing your eyes might be more scary as it is fairly disorienting. If you open your eyes, you will get a better experience and it will feel like more of an achievement as well.
While standing in line, if you're freaking out, tell yourself that nothing will happen to you. If you don't do anything stupid, you'll get off the same way you were when you got on.
Follow all the safety rules that they provide, and know that you'll be fine. You may feel as if you will be thrown out of the coaster, but be aware that there have been few deaths on these types of rides and the deaths were caused by people being careless.
Once the ride is over, don't walk out of there acting like you just went through hell. You don't want to scare other people. Open your mouth a bit like you've gone on the best thrill of your life, and fix your hair as soon as you enter the general public. Don't forget to smile!
If you are nervous, it is okay to scream. You definitely won't be the only one, and the train is usually noisy anyways. Instead of just being quiet with fear, screaming can actually make the ride more fun. Also you can also mix your screaming with some "Woo hoo's". Just make sure those "Woo hoo's" aren't additionally mixed in with a couple flying chunks of your lunch. Screaming can take away the scariness and make you want to laugh.
Some things that could help you are-
1. If you want to try to sit in the front and keep you eyes open then you could pretend that you are "driving" the roller coaster.
2. It is a fact that riding a roller coaster is safer then walking across the street.
3. Roller coasters are checked every morning by professionals. Nothing will go wrong.
4. of the few injuries reported each year from riding a roller coaster, more then 3/4 of them are personal issues like heart, back, and neck diseases that the people had before they even rode the coaster. Just have fun.
If you're scared of the big drops, look for a roller coaster with a curved drop instead of a straight drop. Straight drops are fun, but if you're looking for a tamer ride, a curved drops are the way to go. They're gradual and don't feel as if you're plunging down like it would on a straight drop.
