I said this before when you were struggling in another thread Acrofox. It is totally okay to walk away from all this. I did it. Sometimes I wonder "what if I stayed," then I think about all the friends I've made, experiences I've had, and ways I have grown by my choice to leave. I am looking to get back, but that's less about "oh man I screwed up leaving" and more "I've done my time, I'd like to have some new experiences now, and I really like airplanes and travel." When I look back at the years I spent away, there are life events that occurred which would have been very difficult to handle if I was still an airline pilot. My mental health would have greatly suffered, just like yours seems to be. Admitting this career is not for you is
not failure. It's simply admitting to yourself that another path is a better fit, and going out and discovering what that path is.
Flying airplanes is cool, but being healthy in body, mind, and spirit is cooler. Go find a career in something else that interests you and instruct part-time. You'll actually get to fly airplanes instead of pushing buttons, and you'll check that box for mentorship that you said you enjoy. I teach part-time and I find it very rewarding, although stressful at times. Let go of the "ego" of being an airline pilot like it's a brass ring that when obtained fulfills all the gaps in your life. I do not feel like less of a pilot because I fly a dirty-old Cessna 182 at my primary job. You'd be surprised how much stick-and-rudder skills and spatial awareness it takes to accomplish our mission. It is very rewarding in many ways.

When you have some time on a deadhead or an overnight, listen to Dale's podcasts linked above. He's in California/Nevada and says he's always in need of pilots that won't run off to the airlines. The job he does requires a lot of time away from home, but maybe it would be something that interests you. Maybe not. But it'll possibly help guide you to expand your mindset about what's available in aviation. The airlines and large-cabin corporate Part 91 are not the only games in town. Yes, you'll make less money... but I hardly break $100K a year, and I live very comfortably. In fact, if I were to get back into the majors and make 3x my current salary, I don't know what I'd do with all that money. I love my little house and my sub-3% mortgage. I'd probably donate a lot of it to K-9 non-profits we support. The point is, getting hired at one of the Big-Three and making $250K+ a year isn't suddenly going to fix all the underlying issues regarding happiness in this career. Step back, take a break, meditate, says some prayers to whatever deity you believe in (if any), and seek guidance to the
right path. With time you will find it. I wish you the best of luck!
