In reply to drink_more_tea:
Sorry if this turns into an essay, and hope it doesn't come across as too much of a lecture.
Firstly, there is no concrete definable "meaning of Life" (42 not withstanding). Rather, at least in the relatively advantaged west, we have the opportunity to live meaningful lives; existential angst doesn't seem to be a big issue where folk are struggling to survive. And that's seriously not meant to be a dig at anyone.
So what does/ would make your life meaningful?
You mention the financial difficulties of your childhood and how that motivates you towards financial security. On the face of it that's fine, but "fear" as a motivation is a bit negative. You say you "always dreamt" that you'd be "career minded", maybe you're not and are relying to much on the stick without enough carrot. Try thinking about what you want rather than what you don't want. Bit like skiing/mountain biking, look where you want to go not where you're scared you may end up; you always end up going where you're looking.
Are you staying where you are because you want to be there or because you're scared of the alternative?
You initially imply that you want to go travelling, but later say you had the opportunity of a month away (something few of us could afford the time or money for(again don't take as a dig)), but you bailed after a week. What happened?
(Don't go answering any of these questions on a public forum, just have a think)
You say your partner is out of work. Why? What are they doing about it? You say your partner sits around doing nothing all day every day. Why?
Most of us can sympathise with the idea of needing a day in the house just to catch up with housework, especially if doing 12hr shifts, but why is there anything to be done if your partner is at home all day every day? What are you BOTH bringing to and getting from the relationship? Is your partner consciously or subconsciously sabotaging things, if you do nothing on your days off does that normalise their behaviour for the rest of the week?
Are you staying where you are because you want to be there or because you're scared of the alternative?
Are one or both of you suffering from depression?
Don't listen to the "fresh air, exercise and a healthy diet" crap; if it was as straight forward as that then no sportsmen/women would ever suffer from depression. Don't get me wrong, just as if you were asthmatic that would be great advice and would go some way to reducing the severity and frequency of attacks; it wouldn't cure you and you may still need to see a GP and even take medication occasionally. If depression has a biochemical basis then no amount of organic lentils is going to sort it. Even if you and/or your partner have been suffering from a reactive depression for a prolonged period that can have an impact on your brain chemistry.
If the things that you intellectually feel should make you happy are not having that effect one of two things are likely to be wrong. Either, the things you thought you wanted aren't really the things you need; or your body isn't releasing the happy chemicals when you are experiencing happy things.
Don't feel bad about the odd duvet day; we all need to curl up and tell the world to feck off now and again.
Nothing ever lasts forever.
We're not meant to be happy all the time, it'd get boring; then we'd only be happy when we were really miserable because it'd be a bit of a novelty.
BUT, we do have the opportunity to live meaningful lives that bring us a sense of contentment.
Don't just hang there waiting for a hold to appear, disco leg will get you. Keep moving, doesn't matter if it's up, down or sideways; you'll find something. Talk to friends, family and don't rule out professionals; sometimes just saying things out loud has an amazing impact (and we all need some beta sometimes). And remember, it's not a first ascent; loads of us have been there and there is no reason to believe you are in any way less well equipped that some of the bumbly old farts that have made it.
Wishing you health and happiness.
