Feeling gutted & lost

I spent the summer working at a lower-tier BB in a rotational program with mandatory rotations across IB and another divison (don't want to get too specific so as not to identify myself.) I was pretty certain I wasn't getting a return offer and then, literally 3 days before the end of my internship a position in a group I really loved opened up. I busted my ass and completed a case study in an asset class I'd never studied before and did excellently according to the hiring manager. However, the manager said that since I hadn't met the team (I didn't work directly with them and had only met one analyst, one associate and the MDs in the 3 days I had) they'd only be hiring one graduate. I honestly feel crushed and like the walls are closing in on me, the firm mentioned roles might open up in some of their other IB teams but I feel like everything is falling apart. I got stellar feedback from my managers and HR mentioned repeatedly that they want to see me back at the firm, but I just feel crushed. If roles don't open up at this firm I don't want to move downward to an MM because of exit opps and dealflow but getting a spot at another BB in an IB/structured lending/private credit role seems like it'll be an uphill battle. I really just don't know what to do and I feel so lost. I busted my ass over the summer as I don't have a finance background, I'm not in any finance clubs and I taught myself and learned basically everything from ground 0, often pulling 18+ hour days to better understand the asset classes and technical aspects. Am I cooked?
