Basically slept through FT recruiting - wtf do I do?

Hey all, I'm going to get straight to the point. No hiding it, I was a complete dumbass this recruiting season. Like full retard. In a nutshell, I had such a negative experience at my boutique (MBB-esque) consulting firm junior-year intern summer that I (pretty much subconsciously and intentionally) completely missed basically all OCR deadlines/all deadlines from August-November. I can beat myself up for it all I want, but I can only chalk it up to stupidity, a weird depressive episode, self-sabotage, and sheer immaturity. Essentially, an angsty teen phase. To make matters even worse, I may have badmouthed the company a little bit, so no support from them ( I know, I know, STUPID )

For some reason, after my internship I thought I was "jaded" with consulting and business, that I dropped my biz econ major for a humanities major which makes things even worse Can't tell you wtf I was thinking but alas. Because of the caliber of my past internship, I know I would have gotten at least a few first-rounds at the firms I didn't apply to. It just feels so frustrating because it's not that I was rejected, I rejected myself by not even applying.

I've been deliberating, and here what I think are my options:

1) Try and get SOME job offer ( even if it sucks ) and get into an MBA program down the road. Recruiting after the Fall semester has proven to be incredibly difficult. I've had a lot of interviews but no offers. There is a legitimate chance I may end up not employed by the end of the school year. My standards have dropped significantly and I'm basically applying/networking with literally any job I can find. MBA admissions might also be tough bc I'll have to explain why I dropped biz econ at ug. I have a final round for a pretty prestigious fellowship but absolutely no guarantees for an offer and if I don't get this DAMN it's rough out there. Anything now is a pretty massive step down from what I got last summer. It's been really tough without a Business/Econ major even with my work experience. Balancing recruiting and this is also starting to take my hit on my GPA, dropping it to a 3.5.

2) Try and get SOMETHING, study my fking ass off for GMAT, and then apply for an MMS/MiM/MM/MSF at Duke, Ross, Stern, etc. With my past internship, I think I have a somewhat decent shot at these. The only thing is explaining why I dropped biz during undergrad. Not gonna lie, a fresh start at a new school sounds really great right now. This will basically make up for my lack of business background. However, this also means 50k+ in debt I'll have to eat up for basically the same recruiting pipeline which is not great.

3) Take an extra semester overloading econ courses and go through recruiting again. I won't be able to say I'm an econ major bc I can't finish it, but maybe I can say I have a minor? Or "working towards" an econ major? idk. Internship recruiting is a bit later, and I already have consulting experience, so I can probably snag something (probably not brand-name, but something) for this Summer. Not sure how this works with financial aid, or if I'm even allowed to do this as but something to consider.

4) Take an extra year overloading in econ courses to try and finish a major in econ, then go through recruiting again. Again, not really sure how this works for financial aid. Not gonna lie, this is something I would really like to avoid because spending a whole extra year at this school honestly sounds miserable.

5) ???

Which path do you think I should go? I need to decide soon as graduation applications are going to be due very soon.

Look, I get it. I made a stupid mistake. Scratch that, A LOT of REALLY STUPID mistakes. Not gonna lie, I kinda feel like a failure, like I wasted 3 years of good work. I already know that. Honestly, things have been really tough and I've been beating myself up for a while now but at this point, I gotta make the best of it. I'm not gonna pretend like I'm some victim. Ugh, I feel like I had my shit together until last year and it's going into hellfire now. Hey, on the bright side I fucked up this bad so I know absolutely everything about what NOT to do from here on out lmao. Haha, I promise I'm smart, but I may have a bit of a self-sabotaging habit that I'm working on.

Please help me figure my absolute mess of a life out. Thank you so much. Happy new years y'all haha
