Having a difficult time finding self-worth/ need advice

I didn't receive a return after interning for a TMT team at a fairly well-known HF (think Baupost, BAM) this summer due to a few reasons with the virtual environment being one of the key reasons.  The opportunity to work at HF was too good to pass up on and I rejected an IB SA offer last summer, and my thought process going into it was I would be able to recruit for FT worst-case scenario. Coming from a no-name college in NJ and a poor background, I worked as hard as I possibly could and after being rejected I am having a very difficult time assessing my self-worth, often questioning whether I really know anything or if I just BSed my way through life. The amount of anxiety and stress of not having a job lined up is starting to take a toll. It's already a few weeks into IB FT recruiting and without a single interview, I'm hopeless and I don't know what to do.
