Resume Just Been Gutted - Please HELP

Hey guys, apologies in advance for a long post.

Background: I do not want a job in IB. I'm specifically looking for a job at a Hedge Fund after graduation. I just finished my Sophomore year of College at a target school, with a Major in Economics and a Minor in Finance. I thought everything was going dandy but a couple of bad things just cropped up.

Freshman Year: I was Pre-Med during my Freshman year; it wasn't my choice at all, my parents kind of forced me into it and since I didn't have anything I was interested in I did not find an alternative. I was very depressed for my first year of College, and hated everything I was studying (the Pre-Med program at my school meant that I did not actually take only Core classes in the first year, but specifically Pre-Med Classes. Those took long hours, including lab hours and I could not motivate myself for them). Obviously not an excuse, but my lack of motivation or care meant I ended up with something around a 2.7 GPA at the end of my Freshman Year.
Sophomore One: One class that I had taken just for fun in Freshman Year and stuck with, though, was Statistics. And as I learned much more about it and its practical applications, the more interested in Economics and Finance I became. I ended up finally convincing my parents to allow me to switch disciplines. I hit the ground running; I took a summer course in Microeconomics that had to cram 5 months worth of material into about 1 1/2 months, and still ended up with an A in the course because I loved what I was studying. I went into the first Semester of my Sophomore year and continued to do well, ending up with a semester GPA of about a 3.6, even getting an A- in a specific Financial Accounting class that most of my classmates termed a "grade-killer". I ended up getting on the Dean's List that Semester, and had boosted my Cumulative GPA up to a 3.1. I figured that this wasn't particularly high, but my Major GPA was high and I'd simply continue to further boost my GPA again my Sophomore Second Semester. At the end of the Semester, I even landed a summer internship at a hedge fund that I am starting in a couple of weeks from now.

Sophomore Two: Long story short, this semester I did not do as well. I did well on most of my other classes; if not for this one specific class, I would have ended up on the Dean's List again. This was a particularly nasty Econ class; it was not personally classified as high level but most of the people in the class were Seniors, and halfway through the course (!) our teacher informed us that we had to have taken a high-level Macro class to understand this class (which I had not taken, and am taking next Semester). For one of our projects, we were literally asked to base our work off of the foundation of that other high-level Macro class. I ended up with a C- in this class, ending with a Semester GPA of 3.00 and dropping my cumulative GPA back down again to a 3.03.
Problem: This is a large hiccup in my grades that I'm sure looks terrible on a transcript. I'm sure hiring teams and employers can look past a bad freshman year if everything else afterwards is pitch perfect, but this far from that. This is a sudden regressive dip again and I'm not sure that it fully represents the work I put in or the difficulty of being forced to learn a class while simultaneously learn the high-level class I needed for this class on my own time. Worst of all, I'd already dropped my Resume, including the fancy Major GPA that I'd been so proud of, to a large amount of companies I was applying for a 2020 Internship at, which I am now almost 100% sure I will not get because of this, as I do need to do an updated Resume drop now that my Final Grades have come out today.
I have absolutely no idea what to do. Is there any hope left for me / anything potentially open for me for 2020 Summer?

;tldr, bad Freshman Year. Amazing Sophomore Semester 1. Sophomore Semester 2 would have been good too except for one class that made it mediocre. Do I have any time left to fix this?
