Moving to another country for a year after school? Help?

[GabbiiZombii]

So I want to move to another country for a year after I have gone to University because I really think travelling will be a good experience for me, but I'm not sure how to go about this. I have a few years yet, (4 or 5 years yet) but I want to start planning to an extent at least now. But I'm not sure how to go about things.
I live in the UK and want to move to Sweden because I find it beautiful there and I am learning the language.
-How do I apply for a visa, what sort of Visa, I'll be around 21 at the time I go I believe
- * Where would I live, do I buy an apartment? Rent? Are there special places people can live for a year?
- * How could I find a job? Most people would say English tutor, but most people in Sweden speak English
-How could I make friends there? I'm quite socially awkward (which is a reason I want to go, to improve my social skills because I have had a messed up childhood D So i'm not sure how to make friends in a foreign country
The stared (*) Questions are my most important
Thankyouu :3
And yes I have thought about cost and money aspects... I am currently saving for this trip with all money I get :3
