How to overcome post interview anxiety?

I’ve been out of work for 3 months and I had three big interviews. One interview flew me out of state paid for my hotel/flight but also flew out 6 other candidates as well. The 2nd interview was for a startup company and it was more personable. All three interviews I felt confident, I provided examples and demonstrated good speaking skills. Got really positive feedback from all 3 hiring managers.

I just have really bad anxiety to the point where I can’t sleep. They said they would reach back out to me at the end of this week. But what are my odds at at least landing one job?

My nerves are so bad bc I’ve been financially struggling and lying to my parents about my job. I’m so beaten down at this point.
