Recruiting Motivation Died after not getting the firm I wanted

So I was grinding recruiting for months, and ultimately got in to a process for the one firm that was stuck in my mind since before I started my banking job. I made it to the final round and didn't pass, and it was such a kick in the stomach, I just don't feel like recruiting now. In fact I feel like my general motivation in work and in my personal life has fallen off a cliff and I can't figure out how to get out of it. I have more interviews coming and I am objectively working a pretty desirable job right now but I am in this mental rut now. I don't even feel like working out or doing stuff in my persona life at full capacity, which sucks. I feel like I'm just making excuses, god
