Pit of my stomach

I'm not sure why but I'm afraid of work. So it would seem anyways. I haven't a clue as to how I got to this position but here I stand, broken and nervous and anxious all the time. I don't believe that I actually fear work but I'm feel so far behind that I'm always nervous about it. Maybe I'm lazy and don't want to do it? Well how do I work so many extra hours and still fall short? I just need to sit down and do work. I need to get organized for sure and work smarter not harder. I know in a few months everything will sort itself out, but can I make it another few months? Nothing beats working hard, working your ass off. That's how you get caught up, that's how you get ahead. I just need to remember to keep my head down and get everything completed. I'm in need of relief in the form of other employees being hired on to take over part of my caseload but there's nothing that can be done about that on our end. I need to sit down with the boss and let her know what's going on and get back on track. I'm tired of feeling this way. A grown ass man shouldn't have these issues with work. I have a family, hopefully a bigger family sooner than later, and a life that takes priority over this job. Sit down, shut up and focus. Do work.
