How do I overcome this failure?

First things first, I am a (F 27) and since I can remember I've done everything right. I went to school, tried my hardest in college and eventually got into radiology school which I worked extremely hard for. 4 years of my life I dedicated to this program, I suffered emotional abuse and ridicule from my mentors due to the toxic environment of the hospital and my underwhelming performance from anxiety, they failed me on my graduation day.

As you can imagine, I was utterly devastated. That was a year ago. My ex partner who was also a manipulative partner never took accountability for anything left me at the same time. Back then I called it a huge loss now with some therapy and time to reflect I'd like to think of it as a clean slate in the one year since all of this i've managed to go back to school become a phlebotomist applied to a bunch of other programs that I was rejected from got my license as a phlebotomist now awaiting jobs, and unintentionally fell in love with my best friend which at first, I was extremely hesitant about, but turned out to be the best decision I ever made. I have never been as mentally healthy as I am now. Once a very insecure, jealous partner I'm now the most securest I've ever been.

So some would say I won, as much therapy as I do I like to reflect on those times and how I went wrong and I can't shake the feeling that I'm a loser, that I let my family down and that no one should take any advice or look up to me because I completely failed and I had to start over taking a lower pay than what I would've made. Sometimes I say hey it wasn't meant for me and I move on another days. It makes me upset and I can't shake the feeling. Any advice?
