Affectionate-Let-979's journey

I recently went through a phone interview, a one-hour test, and then a one-hour interview for a position I was really excited about. After the last interview on Wednesday, I was asked for references, which felt promising. They mentioned I would hear back by the end of the week, but now it's Sunday and I've received no news. To make matters worse, I noticed that the job posting on Indeed, which had been closed, has been reactivated. This has me feeling anxious and uncertain about my chances. Should I just give up on this opportunity? I can't shake the feeling that I might be getting a rejection email soon, and it's frustrating to have my hopes up like this.
