I don't want to sound insensative, but do you want to be a pilot or not?
It is a good healthy fear, don't get me wrong. But having something like nerves preventing you from doing what you (like others) have dreamed of doing, that's bogus.
Think of it from this perspective. You are flying on your flight instructor's certificate. He/She should not sign you off to solo until you can both say that "I know your/I'm ready to solo." Not "I think"...its "I know." He/she should NEVER put you in a forced position.
Anyway, I know soloing is a HUGE resposibility, but if you really want to be a pilot, and really want it BAD...I think after one time around the patch in an empty plane, all your worries will vanish.
Good Luck Chief.
