Hi Nicholas,
As many have said, you are in a good position, despite being miserable in your job. However, I think misery counts for a lot :) I was headed down a similar-ish path: degree in Psych with the plan for a PhD in clinical work. However, I started college at 16, and in my 3rd year of school, discovered RE. I ended up getting my broker's license and dropped out of school after 3.5 years, which lead me to investing.
I'm very fortunate that I realized the traditional path wasn't for me early on, before I took out a ton of student loan debt (state paid for my college until I turned 18, which was an AAS). Anyway, my point is, I don't think you should "get out of the millennial mindset" of wanting and expecting job happiness. Every job is going to have some degree of awfulness, but if you are truly miserable, then why adopt the boomer mindset of working a terrible job until you die? That's kind of ridiculous advice, haha.
Now, I don't neccessarily think you should just quit your job, either. You have a high paying job and likely a lot of debt. The good news is, since you're not trying to climb the corporate ladder, it kind of doesn't matter if you jump around to different companies or whatever. All you need is a paycheck and W2 income. My thought is that moving companies or slightly changing positions every once in awhile may give you enough change to keep you somewhat interested in your job until you are able to "retire" with RE. Also, maybe re-framing your mindset from "I need to get out of this job" to "I do this so I can buy RE and retire" may help a little bit.
If I were you, I would do that, while aggressively investing (and paying down loans if needed). Depending on your DTI, you may need to work at reducing expenses (rent/mortgage, car loan or transportation, etc). Bonus points if you can find a semi-work from home job or a job with less hours (assuming you're salaried and your work week is more of a 60-hour ordeal than a 40-hour). Once you lose W2 status (as a RE agent or as an investor), it will be much harder for you to get loans. Use your license to buy your own properties, and also to learn as much as you can about the business. Maybe work on slowly building up a client database and network, so that when you do quit, you'll have an easier time transitioning into sales.
Hope that's helpful. Sorry that you hate your job, and best of luck!
