I'm 29 and only recently in the financial position to possibly buy a flat alone. I've never been in a relationship and have no interest in being in one/don't see myself ever being in one. I have a very small life. I work remotely and have drifted from all of my friends/they've moved away/moved on in life. As a result I don't have any friends.
I currently live with family (parents and a disabled sibling who will likely never move out/live independently).
Now that the financial option of moving out is on the horizon I'm wondering if it's even the right move for me and I've started feeling dread about it. I know some nerves are normal with big life changes, but I'm worried I'll regret moving out and it will send my mental health spiralling. I work fully remote. I'm currently a 2 hour commute away from my local office. In previous jobs where I had to go to the office once a week I ended up having a breakdown, partly due to it. I really struggled and would often cry on the train home from it. I think I'm likely autistic. So getting an office job for more social interaction isn't really an option. I tried living with flatmates in my 20s but I hated it. I'm very private/introverted.
I do have a dog who will be coming with me if I move out so I won't be fully alone, and he will be a reason to get out the house everyday and hopefully I'll get speaking to people that way. The places I'm looking at are only a 10 minute drive from home.
I'm really not sure. The only other people I've known who live alone have all had lots of friends and a partner so they'd have people round several nights a week and have people staying over. My life won't look like that.
Does anyone have any advice?
