Hights here too...if I'm in a controlled situation, like in a car on a bridge, then I'm fine, but if it's like on a farris wheel or looking over a rail, I'm dying. I get that feeling like I'm already falling and stuff. The worst was in the Arch and in the Farris wheel at 6 Flags STL...the arch got me with the elevator ride...when you look out the window there's stairs that go all the way up and that with the shifting of the elevator car that kinda got to me...also looking out the little windows at the top. The Farris wheel was always a problem with me...my dad loves to swing the car back and forth, and once our car stopped at the very top, I was like 8 at the time, and it was honestly my first time up there, and I was ok if I didn't look out, and then my dad started rocking the car(at about a 60 degree angle each way)and I just lost it...I started screaming at him and actually sat on the bottom of the car till we got lower down...
Ohh and the Rock and Roll hall of fame in Ohio...there's little floors in there, about 6 floors in the place, and the rail is all glass and the top 3 floors have stairs(there's elevators too) and they jut out from the floor overhanging the bottom level some 40 ft below, and it's all glass and me and my mom just couldn't do it...we took the elevator.
Really, nothing else gets to me...I'm sort of anti-claustrophobic, I like cramming into boxes and stuff...the only other thing is the dark...like pitch black because I can't see anything and if it's quiet it also kinda gets me on edge.
