I haven't posted on here for so long, but I'm feeling desperate for some life-changing advice (no pressure!).
These past 18 months have seen unforeseen issues arise with our kids (my teen DC, teen SDC and nearly-three-year-old); work upheaval (me changing job, job now at risk); my eldest's involvement in sport really take off (regularly taking me far afield on evenings and weekends); our little one still sleeping wakefully (I am always tired and lacking energy); and a build project on our house that we're doing ourselves (no money for builders) almost grind to a halt.
In all this, our home has become a staggering mess. We've never been brilliantly tidy, but have reached a new low. Lots of stuff doesn't have a home, lots of stuff that has a home isn't put back where it belongs (by any of us - we're all naturally messy), many days are too busy with work, sport, little one, DIY (or I'm too tired) to clear up after dinner, sort laundry, sort paperwork, tidy up the little one's toys... and so it all builds up.
Unless I have a rare opportunity to blitz the place, we are always in a shocking mess. And I mean really shocking - not your light lived-in mess. We have to step over random stuff just to walk across our living room, rummage through the sofa laundry mountain on busy mornings to find two (mismatched) socks... it's utter chaos. And CHAOS in the FlyLady sense too (Can't Have Anyone Over Syndrome).
I don't have people over anymore. I'm too ashamed. I feel disconnected from my friends - socially isolated. It's miserable. I get invited to others' houses with my little one, but I never reciprocate, which must seem rude; we 'owe' a few dinners and get-togethers. Eldest DC said recently that it would be nice to have some family friends over soon - "but only if you're OK with the state of the house, Mum". This isn't the home I envisaged for my family. 
I am so desperately unhappy. The state of my house, which I want to be a warm, inviting, calm, enveloping sanctuary, is making me depressed. I dread coming home from being out. I'm sure my mood is impacting the kids. I have told DP, and the older ones, how I feel, but it's not enough to effect any change – the teens are in their hormonal, self-centered bubbles, and I must sound like a stuck record.
DP does what he can around his work, the unending build project, and the kids. But anything beyond a sporadic kitchen clear-up, sweep or laundry in the machine/on airers bottle-necks with me. (And DP naturally gravitates to working outside in the garden - which is important, but I think inside matters more.) And we haven't found a workable, fair chores rota for the teens, because they have such different schedules, amounts of homework/free time, length of school day, distance to school. Plus they resist requests to do chores. So the state of the house is mostly down to me, and I feel utterly overwhelmed. I can't see any way out.
Next week, I'm using up annual leave, as is DP; we'll have a few child-free days to clear up the house. I plan to do FlyLady's crisis cleaning, which has worked for me before - at least to quickly get the place tidier and possible to clean. I've also figured I need to (1) declutter as I go, (2) organise better and more storage (this weekend), (3) put stuff away and then (4) clean - that's my four-step plan.
Does anyone have any other tips on how I/we can achieve some amazing results in just a few days? Perhaps more importantly for my mental health, how can I/we keep our home a more pleasant place to live day-to-day? How can we keep it more or less guest-ready? How can we get our older kids chipping in more and doing their fair share when their daily routines and free time vary so much from day to day, and between each other? What non-negotiable rules do you have for your teens that help keep the house in order?
I don't want to feel the ground-swallow-me-up shame anymore when people turn up unexpectedly. I don't want what I achieve next week to unravel within days, as has happened before. And I want to invite my friends round over Christmas; I miss them.
I think if I can't achieve something transformative off the back of next week, I'm going to have a bloody breakdown.
Thanks for any tips, general hand-holding and ideas that will change my life!
