Don't worry about being worried or scared of heights. As you found out, being at the controls is different.
30 degree banked turns used to get me very worried.
I've been flying now for over 20 years and have 600 hrs and compete regularly in aerobatics competitions.
I still have a problem with heights if I stand near the edge of a cliff and look down or even if I am with someone and they are standing near the edge.
Flying is different somehow, I overcame the worries after just a few flights and I'm sure you will.
On the other hand, as everyone on this Forum will tell you, Flying is a very addictive and fairly expensive drug. You'll cetainly be better off financially if you never do it again!!
