Tips for newly married and adjusting faster?

I'm 26F and getting married in 4 weeks, (semi-arranged our parents found each other and then we talked for a while) however I will be leaving my hometown and moving to a new city 4 hours away (by plane) I will be living in his parents basement apartment, while we save to move out.

I'm wondering if anyone has any advice on adjusting/getting comfortable quickly? I'm not great with change and can be pretty shy I'm worried that it'll take me a full year or two too settle and that I won't be able to enjoy anything untill then.

I'm also a little worried because he's pretty social and I have to get on with his friend's wives , his parents, his siblings (all older and marriageable age). His family all seems very nice and have been nothing but kind in our few conversations but I still feel awkward and don't know how to get comfortable when I get there.

I'm just scared cuz I'm starting from scratch im leaving all my friends, my parents, my siblings for a completely new place where I don't know anyone or anything.

Sorry for the long spiel, if anyone has any advice on getting comfortable in a new place with new people and creating a bond with their new spouse while not feeling awkward in his parents house I would really appreciate it!!
