There are a few guys in my club that have what I call performance anxiety. Their worst enemy is their own mind. Crashes become a self fulfilling prophesy.

I'm not saying you're to this point, but it sounds like you're heading that way. I would suggest taking a break for a while and getting back to the sticks with an airplane that you know you can handle and that you don'd mind losing. I also put hundreds of flights on a BigStick 40 way back when. You can't beat them for reliability.

The key is confidence. Work toward getting that back by taking comfortable steps. I also agree with trying some IMAC or sequence aerobatics. This, more than anything else, has honed my skills and created confidence.
