There have been similar threads to this already. Believe me, I've read them all several times. I still feel like I need to get my thoughts out.
I cancelled my flight lesson yesterday. I've got 25 hours (all dual), now flying weekly but I started with twice a week. I've been feeling distractedly anxious the day before every single flight and worse the morning of the flight. I've considered quitting, but then I read some encouraging examples of others online and push through it.
My anxiety seems to be from two main things.
1. Perfectionism and frustration at making the same mistakes repeatedly, plus not soloing yet.
2. Trepidation at being PIC, making mistakes, putting others in danger. I'm doing this for fun and because I love being in the air, and the responsibility seems to suck all the joy out of flying. I'm afraid if/when I get my private, I will avoid taking others up and eventually stop flying due to this pressure.
Yesterday, I got up early to do my flight plan for my second dual cross country. We are doing them to take a break from the pattern until I can get crosswind landings figured out.
I made a stupid mistake, like using my first true course as my wind correction angle, and had to redo several things. At this point I started my mind started wandering to the what-ifs, as in "what if this happened and my CFI wasn't there to catch it". I felt a little panicky and it broke my concentration. It was almost time to leave and my flight plan was only half done, I didn't have my weather briefing yet. All that, coupled with the doubts I've had for weeks just started overwhelming me.
Anyway, I ended up in tears and feeling so stressed that I called my CFI and cancelled. He seemed surprised, said I was a good student and not a slow learner. He pointed out that I already passed my FAA written and all my part 141 stage quizzes, so I've got the knowledge part down. He thought I was being too hard on myself, especially about the landings. We kept my next flight in two weeks on the schedule and left it at that.
I knew this was going to be hard work, but I didn't realize how stressed out I would feel. When I'm in the air, I do enjoy it until I have to land, or I'm drifting away from my heading, or I can't understand ATC, etc. This was supposed to be for fun, but I'm anxious about it to the point of avoiding thinking about flying during the week.
