I Hate My Life

SO, I have an MSc Medical Physics. Not very useful it turns out, unless you can afford to train - and kept up to date with it.
I have a degree in Physics - 2:2 - not worth the paper it's on apparently.
I can use Office applications, including basic VBA to automate KPI monitoring and lock down spreadsheets.
I can use AutoDesk Inventor to produce General Assembly drawings and detailed manufacturing diagrams.
I created the CAD data section of our ISO 9001 quality management system and had loads of good ideas that were implemented to reduce quality issues and increase efficiency.
I have experience in New Product Introduction, from cradle to grave - working with international standards, precision engineering experts and international experts in the field of medical physics. This was all in person and by email/phone.
I got a double pay increment (from £19 to 21k a year) one time because I'd contributed so many new products and saved the firm a shedload by persuading them to invest in CAD (and, therefore, me).

So why am I a failing shift manager at McDonald's, working a crazy ass randomly generated schedule that's killing me so bad I left my bike outside the back gate last night (forgetting to bring it in) and it got nicked?

It's not for lack of applications. Quality applications, I've been told by more than one careers advisor. I had one interview this hiring season (it's January in the UK). They chose someone with more current CAD knowledge for a physicsy application, rather than the guy with a masters in a physicsy subject.

I've traveled to South Africa (in the bush) and volunteered there upgrading their server and PC's, teaching them housekeeping and leaving them tools to help their data collection.

I have an innate ability to listen to someone's troubles, leave my own life, mentally live theirs and within about a second have the perfect answer tailored for them, so they can understand it, see the potential outcome, and often execute it and thank me after. I call it the groundwork of life - most people take it for granted, they haven't admitted anything's dramatically wrong, it just comes out at me and I happen to fix it for them, and they carry on living seamlessly as if nothing was ever wrong. Only I have actually witnessed the pain it was causing them, and only I know the benefit I've had. Quite often it works that way. But there's no career in that, it doesn't exist to my knowledge. Not without an expensive training course and the risk of not being able to pay back that loan when I'm already broke.

I support (mostly mentally and raising awareness) multiple causes - zero waste, organic food, sustainable agriculture and packaging, anti-nuclear (think Fukushima's latest leaks!!), anti-extreme capitalism, rain forest protection, keeping our NHS public and creating a decent state-owned infrastructure, real education (logical thinking, intuition), etc.

I just wish I could find a place in the world, working towards one of these causes. And I also wish I could become a better shift manager right now - and not work this crazy schedule. I wish my back wasn't killing me 24-7 because of bad mattress choices (although one was £500 and one was £60, they both have the same results).

I'm slowly dying here, feeling stuck, lost and alone although I am engaged to be married and looking to buy a house together! And I should definitely be asleep right now because I'm on the overnight tonight. z_z

Anyone got any bright ideas out there?
Anyone at all.
