Hi there sorry to hear you are having a rough time. It can ferl overwhelming at times. I do think that yr older ones are old enough to have a meaningful discussion about moving to the downstairs bedrooms. If you sell it to them positively it could be really exciting for them to get new rooms and the added bonus of a clean out at the same time. Maybe book a council clean up now, they usually book 3 or 4 weeks ahead so you have time to plan the bedroom move. I usually go to bunnings and collect 3 or 4 empty boxes and fill them straight away and put them in garage waiting for cleanup. Then go for more boxes. I am pretty ruthless. Also, how about utililising daycare and oosh if its available and getting a job for a few days per week. Its a great feeling getting out and about rather than drowning under the usual household dramas.. thats what i find anyway. Working gives something just for yourself. Just some ideas... all the best.
