I feel like I am wasting time at my job. I feel like a coward for sticking around. I just don't know how to leave. It's a good paying job but I'm burned down. I cry on my way to work every morning and even on my lunch break. I want to take a leap of faith and put in my resignation letter but I'm afraid to lose that security.

Have any of you left a job that was secure for something that wasn't?
