Opinions on living alone, your experience living alone for the first time?

I'm a huge fan of having control over one's own space, to such an extent that even at times that I've been living with others (lovers, friends, cohabiters, family...) I've been pretty precious about carving out "my" space and time within that. I've lived alone and I've lived with others and the difference is what you make of it. I've had times I've been living with others and have missed living alone, but nowadays I get the best of all worlds: living with people I love, but who understand me and the fact that sometimes I like to go hide away by myself and/or do my own thing completely independently!

The single most important thing to remember, if you're nervous about living alone for the first time, is that nobody on Earth knows "how to adult". I've over twice your age and I'm still bumbling my way along, making mistakes and learning from them, having no idea how to do things and having to work it out on the fly or ask somebody. So don't beat yourself up over it when you discover that you don't know how to pay your council tax or read a water meter or clean the filter of a dishwasher: nobody's born knowing how to do any of those things, and sometimes you just gotta learn. (I've picked three completely arbitrary examples: for all I know you've got them all in-hand already!)

The second thing is: especially if you're used to a noisy and crowded environment, moving to your own place can feel very quiet and empty. Even, perhaps, isolating. Don't forget to reinforce the connections to the people you already have in your life (set up that next video call or in-person meeting so it's in your calendar, or make a point of leaning into your digital communities) and consider taking advantage of the opportunity to explore new ideas. You made a good list of free/cheap hobbies the other month: that's great - if it were me I'd be looking to see if I could add one "new" thing to try, especially one that gets me out and about and exploring my new neighbourhood... feeling outdoorsy? hint nudge geocaching/geohashing nudge hint

But yes, to recap: the important thing is that it's okay to be nervous, but it'll all work out. Nobody can predict what'll be different or challenging for you specifically, but so long as you come at this step with an attitude of curiosity and self-growth and a willingness to work-it-out-as-you-go, it'll be a fun adventure.
