Why can't I find some photos in Photos when I try to attach them to an e-mail?

Good morning! I would really appreciate it if someone is able to help a recent Apple convert here...

I have an iPhone 5S and a MacBook Air 2014, both with up-to-date software. When I take a photo with my iPhone, then open Photos on my MacBook, the new photo appears there. Excellent!

BUT...

Then I open my Gmail and try to attach this new photo, OR try to upload it onto Facebook, and the photos that are displayed are different to what shows up when I open Photos. Most of my older photos show up, and a few of my newer ones, and even some photos that I've deleted from Photos! But not all of my newer photos!!! So I can't send it in an e-mail!

PLEASE can someone help me... this is so frustrating!

Thank you in advance!
