What is your job? 13 hours ? really? i suggest you to change your job to find something you really like.
I'm too old for that. I chose a career that is very intellectually demanding and needs a lot of team work. I think I highly overestimated my IQ at university, I thought I could overcome my handicaps with hard work, but that never happened really, and I never could become good enough at my work (good enough to move between companies or be confident at interviews, etc).
Dude - I totally feel you. Right now I'm only working like 43-45 hours a week but for a long stretch back a few years ago I'd be pulling 60-70 hours weeks. My max number of hours ever was 73 in one week. Some days I'd come in at 9:30 and leave after midnight. There was one month where I worked 3 weeks, 21 days in a row with no days off. had to work Saturday and Sunday for 3 weekends in a row. So I know the type of stress and misery you're going through.
One thing that really upsets me is that my colleagues, and managers and so on, are all okay with this inhumane workload. I used to work at a small company that got acquired, and things have become unbearable ever since.
On paper, I'm only required to work 9 hours a day, but the workload would simply never fit in that time. And I guess the easiest thing for them to say is that we're not working efficiently enough and it's our fault. It's so disgusting honestly. I feel zero investment in the company, actually negative investment at this point.
Any chance you can move into another role internally? I also was (am still) in the same boat in that I'm deathly afraid of leaving my job or getting laid off because I don't feel like I could get another one. But maybe it would be doable to move around within the same company, that might not be as difficult as looking outside the company.
I don't really know. I've tried that before, and it sort of messed up my resume, and my "actual" experience (because I spent a few years doing 'easy stuff').
