David:
I've been where you are - looked into the abyss. Got severe TLC ( total loss of confidence ). I didn't stop and climbed the greasy pole. Lots of encouragement from the family. "If you give up now - don't bother coming home after the money you've spent" Reached the apex of private flying. Watched glorious sunrises emerge after breaking through 10000' of solid clag. Got really choked up looking at the Northern Lights, flying out of Bergen, listening to Thunderclap Newman coming thru the ADF. Seen the inside of a big CB over the North Sea at night, in an airway - all on my ownsome. Shutdown duff engines, tussled with engineers over C of A flight tests, several renewals with all sorts of examiners from grads of ETPS to 16000 hour seen it all - done it all types. All with their own idiosyncrasies. I tell you this all pails into insignificance if you consider your alternative.

This activity will truly drive you to total despair. Keep flying - it's easier and if you want a bit of "ferapy" buy yourself Top Gun and play the "Mav's re- engaging" sequence a couple of times
You will feel better in a few months and remember - you are the guy with the wedge. You do have control and the future's bright.
