Re: What is my problem? I have a hard time riding rollercoasters
You could have had a shortage of oxygen. Some teenagers are now intentionally causing themselves to black out during roller coaster rides for the thrill of it, of course it can be deadly or damaging. Dr. Phil had a show about this. Depending on the type of roller coaster I guess it is possible to be deprived of oxygen without trying, especially if you panic at all and hold your breath without realizing it.
A lot of diagnoses
Only by the grace of God do I keep on going
