Ever since I was a child, I've never been able to ride roller coasters. It *always* gives me a panic attack, even if it's a ride I've done before. I can do *some* thrill rides (Forbidden Journey at Universal, Indiana Jones at Disney), but actual rollercoasters I can't do. 

Curious if A) this is a common thing with anxiety, and B), if it is, can you learn to enjoy them? 

Or is it nothing anxiety related, and just a need to enjoy adrenaline rushes?
