I work part time and I'm already miserable and exhausted. I don't think I can take an extra 15 hours per week, but circumstances may be changing for me and I may not have a choice. And I don't think I can do it. 

"Well just find a job that you like!"

I can't think of any job that I'd like. I can't think of any job that I would want to do for 40 hours a week. I don't even have the energy most days to bathe or change my clothes. I'm working toward a degree that will enable me to get a job doing something that doesn't involve being yelled at on the phone all day and that will pay better, but is there even a point? It's still going to be the same shit every day, 40 hours a week, until I get old enough to retire or society collapses, whichever happens first. I think I'd rather just die now and get it over with. I don't understand how people don't off themselves en masse when all they have to look forward to is selling most of their lives to corporations that don't give a shit about them and give them pennies in return. What a bleak, pointless existence.
