I'm in exactly the same position - 15 years busting my butt on regionals, just made it in the big league and got ditched after a restructure.
I'm considering studying Law, and going back and concentrating on Aviation Law or Psychology and getting involved in Human factors in accidents and incidents.
I've heard, (in all seriousness), of blokes in a similar position going and working on fairground equipment. It pays good wages, requires same attention to detail, as you can imagine, and is far less stressful. Apparently, big fun parks just love ex-aviation mechanics.
