In reply to TheseKnivesMan:
Can only wish you good luck. I did the same professional job (though it was immensely varied) for 24 years, loved it till 3 years ago, still like the clients, most colleagues, but one or two <ahem> Aspects got to me. At the point of about to be going off work with stress, I realised I didn't have to stick with a job that was making me ill, and I wasn't enjoying. I don't have kids, I'd saved up (early retirement fund was the idea, bu instead, I could just not work for a year or two), and my wife god bless her wanted me back to normal (and earns an ok wage herself). So I walked, from a permament and professional job.
After 2 months decompressing, doing a little DIY, and not worrying too much, I'm doing a wee bit of lowerkey (very poor pay) work, like a couple of days a week, and not fully answering questions about my previous life. I've got an idea about future direction (but I'm not telling everyone), and I have to accept I will never earn the sort of money I did before (sounds amazing, actually about average UK wage I believe. But I was never a big spender). But my non-work time isn't dominated by work or it's ghosts. My wife is happy. And she sometimes ets cooked for now.
All this to say good luck, something will be there for you, and to continue in your misery is the wrong way (though I don't know what the right one is). I appreciate I'm lucky to share costs with my wife, and without kids I'm the first on her list. I currently worry about friends of mine in NHS, education, public sector, who seem stressed, hassled, bullied, but don't have the choice to stopfor a while, so are signed off with whatever is wrong "with THEM".
Hope you will be lucky too. You certainly have a lot of sympathy and love on this thread, UKC can be lovely people when the chips are down <awaits troll>
