Like if you're a personal pilot for one of them rich fellas? Or maybe you could help teach flying.
It sounds like public air transit is one of the worst positions to be in now. Sorry man. I've had a friend in that industry and I don't know how they keep from going postal.
You might not even know how much your job is affecting you until you try something else. But it's definitely worth finding some ways to manage stress no matter what you want to do, anyone could get to the point where things are getting to them, and it really makes a difference to be able to handle stressful situations and keep your focus.
I hope you find what you need and that things turn out better for you. I've gone through some rough situations too (I didn't even have internet for a while) but you come out of it... don't be too hard on yourself in the meantime.
