I feel ya! I have been at the same shitty job for 17 years since I was a kid. I hate it have thought about quitting many times. I have no skill set besides what I have learned at my work, which does not transfer to very many places. I am also in a rut and have a shit attitude. I am also the only working person in the house with six people in it. It's rough, and it sucks. But I drink a lot of beer and that helps. I have the same "fear" of leaving my job, as I would not be able to find a new job making what I do now. So don't feel like you are the only one out there, there are many people who are searching for something better. I hope that you can find what you are looking for, and maybe we can both find the courage to face our fear and move on to better things.
