Career Help - Disappointment

Well here's a quick summary of my FT recruitment process.

Note: I will not say anything about where I SAed considering how easily I may be identified.

In summary, I've accepted an offer at a small mm bank ( Stephens, BGL, Capstone partners, KeyBank, CFG, Stifel). I'm a non-target with good experience who lost the FT offer due to cuts (no interns got FT offers in my group).

Over the summer, I had developed a good relationship with 7 or so solid groups who were going to interview me, but 4 of them ended up not taking additional FTs with the evolving economic conditions. Of the 3 left, two were in areas I didn't have a chance in (EB RX), and the final one I did well. However, this firm decided to go with a "less risky candidate (target)". I did well enough in that interview though, where I was referred to another bank by one of my interviewers in which I now have the offer. I was banking on the 5 non-RX interviews.

With no more foreseeable interviews, I decided to accept my mm offer. All 7 places mentioned were BBs and EBs. I am grateful that I broke into IB, I enjoyed talking to my future team, but god I can't shake the feeling of wanting more.

I honestly feel depressed with how hard I worked over the summer and throughout college. 

If I were to lateral, would I have to have a year of experience? Yeah, Ik it is arrogant, but I'm too insecure to think that this is where I got considering how hard I worked. I had goals to exit into umm/large MM PE firms, but I don't know what the process for that will look like anymore.
