You must find a way,  you'll be alright!

Ohh ok that makes sense  You're right it's been only a few days and I don't know how I'll be able to wait for months 

The way I read it was that they put their separate forms in separate envelopes, all within one bigger envelope. That isn't different than what I did, which was putting them all in their own labeled folder.  
 
I see no reason why the people of the department of treasury would decide to split it into separate shipments. And even if, for some reason, it would be processed separately, then the adjudicator can see exactly where the other half is and who has it and retrieve it. That's also what happens when you don't file it concurrently but separate with the NOA1 from the I-130. 
 
In short: worst case scenario it'll delay the adjudication a bit. 

I wouldn’t stress about it if I were you. I think you’ll get a confirmation in about a week (assuming you’ve filed G-1145 with it), but some people had to wait up till a month to hear anything about it. 
 
Meanwhile try to find a distraction. 

They don’t deny for that, once the officer get’s your app he will go true it and see what’s missing and request what’s needes! 
Nema na čemu! Sretno!
