i am 3 weeks after having surgery- i completely understand what you mean; i went abroad for mine to Istanbul and after 4 days came home- all the time there and flying back felt like i was in my own little bubble and world but i made it ahhahaha x
When i got home and saw my little ones and mum and that I felt so so strange and everything was hard to explain to them of what it was like and what had been through etc- since then am back to work and normal life has resumed as in routine wise- i think this very normal to feel like this you know and just each day/half day at a time, every blessing to you x
