Afraid of getting on this rollercoaster? (Pic Included)?

The first one looks like the Rattler and I heard it can bang you up pretty bad. I'm going to Fiesta Texas this Friday and am also pretty scared of going on one called the Scream. I've ever only been on two rides at Fiesta Texas: Bugs Bunny White Water Rapids and the Roadrunner. My advice is just don't think about it. The hardest part is actually getting on the ride.
