Need to Vent

I got rejected from a job this morning that I for sure thought I would get. I aced the writing assignment they gave and the panel interview. At the end of the interview, one of the leads on the team I would work with even said they couldn’t wait for me to join their team. They reached out again for verification of my education & references, emphasizing again they were still excited for me to join. This two month-long process (because of all the holidays so I was understanding) ended in a simple rejection letter with the annoying “it was a pleasure but another applicant was chosen. We encourage you to continue seeking out opportunities with us.” Blah blah blah. I’m so fed up with this job market that I just cannot see the light at the end of the tunnel. It makes me question what’s wrong with me?! I just need one chance :( I hope you all have a better day than me.
