Hi, WS! Exciting news about your impending move! Hope it goes really well for you.
I moved out at 17, halfway through college, as me and my bro didn't get on (we are close enough now, and I am 21). I had a lovely childhood, and my parents are just amazing, but I felt I was ready.
First moved into a student house, but hated it, and only spent a term there. Moved into partner's flat-overpriced and so very cramped, no windows! :S It was just miserable. Also, my partner had let his homeless friend sleep there while he was staying at mine, so his dog had papped everywhere, and we had to clean that up-nice!
Left there to move south of the county for Uni 2 years ago. First, a top floor flat with 2 bedrooms which was nice but kind of uneconomical! But our first "proper" space, so that was special.
We were offered a house, then me and my partner split, although we are back together now. So currently in a compact but lovely 2 bed terrace with a little yard for the dog. We even have outside furniture! It's great. Tried to put some yard plants out, but I am lousy at green-fingered stuff, so they are all dead. Except for the weeds, which are thriving!
I don't regret moving out at all. When I was still in my home town, I saw mum and dad twice a week, now I see them at least every 6 weeks, they often visit us, but I try to get up there too if I have study breaks or time off work.
The distance makes me appreciate them more, and I enjoy catching up weekly on the phone. They are looking to move south or abroad anyway, so sticking around would have done us no favours. My bro is in the Army now ("Wo-oooh!") so I see him just enough that we get on fine!
Best of luck, pet x
