Veggaan's journey

I had a Zoom interview last Friday for a position that I'm really excited about. To be honest, I was quite nervous during the interview, and I'm worried that I might not have performed well. Now that it's Tuesday, I'm contemplating whether I should send a follow-up email thanking the interviewers for their time and asking if they need any additional information from me. Some people say it’s always a good idea to send a follow-up, while others think it might be too late since I didn't do it right after the interview. I'm torn between wanting to show my appreciation and fearing that I might come off as desperate. I just hope I didn't blow my chances.
