AIO roommate gushed about the guy who got the job over me

So I've been trying to get a job for the past 3 weeks and it's been so frustrating to go to interviews, shine, only to not get the job. And these are unskilled jobs. I used to work with my roommate at this restaurant so when a position came open I thought it was a sure thing because I was a very efficient and hard worker according to my manager (who no longer works there). Well I didn't get the job and it was a real bummer. My roommate told me about the guy who was picked over me and to me it was adding salt to the wounds of my very frustrating unemployment journey. I never blamed my roommate for not getting the job, but that's what he thought I was doing when I got irritated at him. AIO or should I just be happy for Dakota and keep my mouth shut and keep looking for a job?
