RE: starting over?
If you were having a problem with dumb thumgs, try to remember that when the plan is flying from right to left, that "left is to me" and when flying from left to right that, "right is to me" for aileron control. The key thing is to get back on that horse, carefully, and have fun. Practice lots of approaches from both directions, and shoot plenty of easy touch and goes. Anybody can buzz around and jamb on the sticks, but getting landings down pat is the most important. Once you feel comfortable getting back on the ground, the rest is easy. Any time I have a few weeks off, I'll take a UCD or something I was really comfortable with and get back my own confidence before firing up the new plane or the big bird. We all get the jitters and yips, so don't worry about it. Get out there and have fun.
