Stressed about starting in 2 weeks

I move into my accommodation on the 24th and frankly, I've been losing a lot of sleep over it. I guess I'm more worried of smaller things like what if I don't have a great start or what if I don't get how to use the washing machine they have (ik, feels stupid to worry about that) or where will I even dry my clothes because I have never used a dryer in my life, I usually hang whatever I have up but no room for that. It's just these little minor stupid inconveniences that keep adding up, and maybe I'll seem silly for worrying about them but I am prone to overthinking every little thing. What could I do to help my nerves?
