I mean this gently but you need to grow up. You’ve got kids. Trying to buy your old property back, asking to buy old neighbours' homes, and crying every day is really concerning behaviour.
Absolutely this.
OP, in the nicest possible way, I did think like a pp that 'moved home and I hate it' meant that you had moved back to the UK from the other side of the world and were hating it, and as someone who has moved countries a lot, and has just moved back to my home country after 25 years in various overseas countries, I was about to offer genuine sympathy, because the reverse culture shock can be really difficult.
But, OP, you've moved three miles -- you can still socialise all the time with your old friends and neighbours, and have exactly the same social outlets, shop in the same places etc, and the things that aren't ideal about the house are all fixable. The fact that you were already weeping in the garden as the removal men were still at work suggests some deep-seated issue in you, not anything to do with the new house or village.
Stop trying to magic your old life back. You moved for a reason, and presumably the reason is still there. You presumably still have the big garden you wanted, even if it's overlooked, and the family room you wanted, even if the kitchen needs repairing or replacement, and the extra bedroom space, even if one isn't bright.
