lack of confidence solo flight

I have flown for a couple of years on and off . I am to the point in my
training that I have completed several local xc solo flights. I am
getting ready to complete my solo xc"s and go for my checkride. But my
problem is that it is very hard for me to just drive out to the airport
that is only 2 mile from my office, get in my plane and go flying. It
just doen't feel right.......... I am just a little uneasy or I don't
know what, luckily I have a great instructor " First Officer Roy
Madewell" of Sacramento, CA who has all of the confidence in me and is
very patient. He has directed me to this internet group for possibly
someone with the same problem. Thanks for any input.
