So I bought a mid 2014 MacBook Pro apparently JUST BEFORE the early 2015 one was discreetly released. From what I've read so far the EARLY (not the new one) 2015 Mac can be upgraded easily, but mid 2014 is out of luck. Am I wrong? Is there any way I can get more than my horrible 128GB of storage? I am trying to do After Effects and other intensive tasks with 0-8 GB of available storage (it fluctuates a lot for no apparent reason). I really want more storage as it is essential for school. And yes I have external drives for storing large files, but I definitely need more room for my software to have some breathing room.

MacBook Pro's haven't had a standard mSATA connection since 2013. This likely being the "easy upgrade" you mentioned. I can personally confirm this info since I've worked on several dozen (retail returned) MacBooks over the past year and a half. The recent ones don't have the "easy" mSATA upgrade.
mSATA's are incredibly universal and on par with the standard SSD pricing. Many ultrabooks use this connection and you can easily buy adapters for regular laptops.
We are talking about an Apple product though and it goes without saying that nothing is going to be standard or easy. That being said, a simple answer to your question is, no. The only way to upgrade your MacBook (or more recent ones) is to buy an uncommon PCIe x2 SSD. Which means it's going to be more expensive off the bat since it's not in "high" demand and even more so since the seller probably knows it's intended for a MacBook.
I recommend checking out Transcend's JetDrive since it's a comparable price to the ifixit link. (it's not out of stock, btw.) Except you get a couple extra goodies like an USB 3.0 enclosure for the drive you replace, tools, replacement guide, screws, rubber feet, etc... Most importantly, it looks like they offer a scan to confirm the proper upgrade for your specific model.
Here's the direct Amazon Store that Transcend forwards you to in the link above.
