I also hate being alone. I like "doing my own thing" such as my crafts and all, but I like someone else in the house. We live in a small zero lot line neighborhood now.. the dogs bark at the kids playing, cats, random people walking and .. well every thing. I don't even get up to look most of the time. BUT.. there is a tone to their bark when I know I need to look
My daughters had a hard time adjusting to living in the city.. lots of different noise for sure.
I hope you adjust and like you said... cell phone check... dog check... lights check... you will be fine
