Sorry for the pity-me post. I have insomnia 
We moved a few years ago for me to start a new job. This job is well paid for what I do, or rather what I am able to get away with doing on a day-to-day basis. Is it selfish to throw a job like that away if my heart is not in it? Should I stay and make the most of the money while I can for the sake of my two young DC? Looking long-term, I am probably not able to sustain the job beyond another year or two. It's just not me.
Since we moved, DH has not been happy with his career direction. He resents my employer and the place we live, and this has driven a wedge between us. He earns more than me, is never happy, thinks I can do better than my current job and wants me to have ambition that I don't feel.
We have fantastic childcare, which has been a battle to secure, and live in walking distance to my work. But our flat is draughty and I think it's making the whole family sick. Constant low-level sickness, permanent sore throats, coughs and runny noses. Accommodation shortage means moving is difficult - our only other option would be better located for DH, but in a place where a friend had an attempted mugging last week, coupled with a rush hour public transport commute for me and DC.
I am so so so close to packing a suitcase and leave the struggles we've had to go through to set up our lives here, so we can recover our health, but then what? I think that abandoing our lives with no direction will only lead to more regrets, including the great opportunities DC currently have.
I feel like a fool to give up now, but when my marriage is not working and my heart is not in anything anymore, I don't see the point of fighting to keep hold of a job where I feel like I'm faking it (badly) every day.
