Is it time to go

Yes.Kind of.

I'm assuming you're a construction worker/foreman? I was an engineer. Well, I still am, but let's face it, that's not going so well for anyone. I'm in an unrelated job now.

I know that stress. Honestly, I and everyone I know that did engineering, did a few years on site and then got the hell out of there. The hours, the physical effort (even though we're not doing physical construction work, the hours and hours of walking, climbing ladders and stairs, dragging around setting out equipment etc is absolutely exhausting, on top of the paperwork we had to do), and the absolute stress of it all on top of the responsibility. We couldn't maintain it. I too have had days when I just wanted to walk away, and felt sick going to work and cried all the way home. In my case, I'm female, and there's no way I could have kept going like that.

So, what did people do? I don't know your qualifications, but those I do know went back to college, retrained by doing Masters or short Springboard courses with internships at the end (generally computers based), and then sent CVs out everywhere. Those that I know of who were in foreman positions or hadn't got degree level qualifications went back to education. Did certs or diplomas in their spare time. There are so many options out there now for courses, you could look around for them. There is just no point in going into a job that makes you physically ill, on top of it being very physical. Either that or consider setting up your own small company if you are a craft worker of some sort (I'm sorry, I@m making some assumptions here).

Either way it's going to take time, but start looking now. You've got a good few years of work ahead of you, and no job is worth your health. And in my opinion, most people don't know what stress means until they've experienced construction work at a supervisory level. It's horrendous.
