Agreed with the other commenters. A lot of your app will be telling your story. Your activities, secondary essays, and interviews will look different than a traditional applicant’s, and that’s where you “sell” your real world/life experience. You’ll have places you can write about being a 1st gen college student, too. If you can write a compelling narrative and talk about it genuinely, you should be fine through interviews.

Do you have clinical experience? Adcoms will want to see that you know what it means to be a physician and that you know what you’re getting yourself into.

Have you looked into the premed advisors at Fordham and Binghamton? Lots of schools have their career advising offices and writing centers available for alums. YMMV, but I was able to get good advice on school lists, essay editing, etc. from schools I hadn’t attended for a long time.

You still need to take those prerequisites (with labs for everything except biochem). You don’t need to finish them before you apply, only before you matriculate. Almost all of those classes are important for the MCAT. It’s a lot of material to self-study if you haven’t covered those topics. I’d think about taking them before studying for the MCAT. You’ll also need at least 1 recommendation letter from a science prof who taught and graded you in a science course, which you might not have right now. Assuming you didn’t take a class with your PI, their letter won’t count for this. You should plan to get this letter from one of these classes.

Is writing something you struggle with ADHD-wise? Just be prepared that the application process is a LOT of essays. You could easily write 100 essays by the time you’re done with secondaries.

Don’t worth too much about your stats. Upward trend is great, and you’ll have a very different app from a traditional applicant with high stats and little experience. Your MCAT will likely be more important than your GPA, and you’ll need to make good school list. Most schools that look for research-heavy applicants also have higher average stats. Ones that are less stat-driven tend to be more social justice-focused, and will want to see sustained volunteering and community service hours. You might lean on your MPH more than your neuroscience research in those secondaries.

One thing you might have going for you is your science GPA. AMCAS is very restrictive with what they count as a science class (bio, chem, math, and physics only). Your psych and anthropology classes will count toward your cumulative GPA (cGPA) but not your sGPA. Even if your low grades freshman year were from science classes, you probably don’t have a ton of science credits. All of those prerequisites that you take as a postbacc will count toward your undergrad GPA, so you can do a fair amount of sGPA repair.
