continue or not
I think at one time or another every pilot has the same thoughts as you're having right now. Since you have already overcome the biggest obstacle to training, the cost, I encourage you to push on to obtain your PPL. At that point, if you're not enjoying yourself and are overly concerned you can move on to other areas of enjoyment. I have a feeling that by that time you will reach a point where the fun has really set in and you're a whole lot more comfortable flying.
When I was working toward my PPL it was a lot more work than it was fun. Once you have the pressure of the checkride behind you the fun factor really kicks in and your confidence is at a point where you feel competent to fly the machine.
p.s. If you do move on to other hobbies and sell the R22....you'd shoot me a helluva price, right?
