Moving into Private halls after a month

I'm a second year student and am currently living at home, i've made the decision to move out as i didn't make any friends in my first year due to mental health issues and relied on my friends at home, my friends at home have all started moving away and stuff like that so I'm feeling lonely

I've been going to societies(3 of them) for a month now and have met some friends but always feel second best to their flatmates, which is fair enough as they spend a lot more time together and do a lot of stuff together

I've found a place I really like, the accommodation is lovely and the kitchen was tidy but had plenty of homely stuff that made it seem like everyone got on (possibly friends from last year as the accommodation told me they were second year students), do you think I should move in? I like the idea of moving in with other second years and the flat is the nicest i've seen so far but i'm afraid moving into an already established group isn't a great idea.

You M or F?
What is their mix of M/F?
Is is private or uni hall?
Did they know each other?
Any chance you can meet one or two and buy them lunch?
They may just people to live with and far from best friends. Your expectations should be realistic.
If its a pre existing group then you may find it difficult to break in depending on your skills.
They may or may not do stuff together.
You need to talk to them.
How large is the flat? Interview each other if they agree. If they arent keen or you seem a bit too needy it might not work. Once you sign the contract you are bound for the remaining 48 weeks or however many are left. There are two sides to flats.
