I had gone through a similar phase recently myself. I had worked 4 years (the last 3.5 years as kitchen manager) in a kitchen I loved. Shortly after we got bought out by a company they were making labor cuts, me being one since I was one of the most paid in the kitchen...
I found another job as a cook in a kitchen doing prepared foods for a large corporate company. Working here basically took all my experience and training, and shoved it in the trash. The recipes, the food quality, amount of food waste... all were ridiculous. Combine that with horrible managing style, and lack of work ethic from the other employees made me strongly reconsider this career; I almost gave up cooking all together.
Fast forward a couple months, I found a new job working in an awesome kitchen. Only having been at the new spot a couple months, the chef and proprietors tell me they want to make me sous chef soon (fingers crossed).
Working in kitchens has been a roller coaster ride for me. I believe if you have the motivation, stamina, proper resources, and patience to deal with some of the most !@##*% up experiences... you can always find a place in this industry.
