AnthonyGA,
Thanks for your reply and your ideas. It is not associated with cloud, now it just seems to be height with aerobatics. I'm not really entirely sure what the fear is to be honest. I am not afraid of heights though and never have been. Just a real loss of confidence. I don't think is related to any events in my past, nothing I can think of at least. It is just so strange from loving the aerobatics and not thinking twice about being afraid to this...
I don't think its time to see a psychologist just yet. As I said I wasn't terrified just quite uneasy, now I am on the ground, and will be for a few months, my mind is just getting wound up a little about it all! Probably blowing it out of proportion.
