It'll take a while, but then you will thrive.
I separating from my husband of 33yrs in March last year. I have never lived alone as I got married at 18, so I went straight from my parents into married life.
I remember the moving day, and the whole thing felt so overwhelming, but also exciting. My parents were there helping which was wonderful. Then, around 6pm they went home .... and for the first time in my life I was in a strange house and on my own, and honestly ... I sat on the sofa and burst into tears. It felt so alien.
Now I have a new partner, and he stays over at my house Monday to Friday often, and you know what .... I look forward to him going home 😂 I love him being around and I love the company, but there really is nothing nicer than having the house to yourself, a mug of tea in your hand, a packet of biscuits and a good box set on the telly - with no one else asking if they can watch the MotoGP or questioning why I love Big Brother. It's liberating.
Edited to say, I also found that I excel at flat pack building. I built a coffee table, two desks and two desk chairs, and I have no idea why I hadn't done it before. It's like a jigsaw puzzle with allen keys.
