Overwhelmed but excited.

Hi everyone! I am 10 weeks today and found out that I am expecting two babies yesterday. 
This is my 3rd pregnancy. My husband and I have no family history of twins and I was not taking fertility drugs. I am 30 years old. 
I'm so scared! I keep thinking about all the changes that need to happen such as buying a larger vehicle, we need to find a bigger house. I'm also so worried that something bad will happen to my babies. Now that I know there's 2, I want both of them so badly.
My question is how did you all get over the shock of twins and I was curious if there are any awesome resources that someone has discovered (like an informative website)? 
I already love these two so much, I'm just blown away that there is really two.
