I suspect there is more going on here and you need to unpack what it is, maybe just a reaction to the absolutely terrible 6 months we have all had, or maybe something else that you might need help with understanding.
In the short term, you need to forget about moving back and make your new house a 'home'. You can fix nearly everything you have listed for instance, sort out the driving in (practise, can you put up mirrors), secondary glazing if the road noise is bothering you, paint your bedroom, change the kitchen, put up trellis or plant trees to reduce the overlooking.
If you still feel this way after a year or two then perhaps move then (with a more saleable house too) but not now. Concentrate on your mental health and your family.
I have moved a few times and out of 6 moves, I definitely didn't look back for 2 of them. 1 of those I knew pretty instantly on moving in that it was the wrong choice... but I could never have know before I bought ehm. The other moves still had me wobbling in the first few weeks, even the move I have just made to an amazing house which I know is wonderful and we will be very, very happy in (and in fact are already).
Stop, breathe and work out what is going on. Please don't be like a former friend of mine who keeps moving (and across the country) and is never happy. One of her children was in 4 primaries before the age of 6 (including one where they didn't speak English!).
