I can empathise, it’s a very big job.
We moved during lockdown OP, lost count of how many tip runs DH did, he knew all the staff so well by the time we moved! We were downsizing, and had lived in our 5 bed house for 18 years, we still had a travel cot and stair gates in one of the bedrooms, our two where 19 & 17 at the time! 😂
DS1 helped me to pack up, we got into a good routine of making up boxes, wrapping and packing. The trick is not to look at things, just pack them, mark the boxes well, the room and what’s inside. Also not being scared to throw items away, that you don’t use, need or love. We got rid of so much stuff.
We must have had twenty boxes for the kitchen, and needed to find the one with the cutlery in the next morning, so pleased I had written a brief description on the boxes.
If you are organised, moving day is much easier. Our removal vans arrived at 8am, said they thought if would take till the afternoon to load, they we done just after 11, they said we had made it easy for them. As they cleared each room I dusted, cleaned, vacuumed etc.
You will get there OP, good luck for your move and enjoy your new home.
