Broke up with my girlfriend

I (22m) was with the most beautiful woman (22f) for over a year (mid 2023 - late 2024) we were long distance for parts of the relationship cause she was still in med school. So we ended things in September 2024 after a big fight, we didn't speak for about 2 weeks before we had the conversation about ending things. I made it clear i was willing to start over but she wasn't so it ended. The fight was all my fault and everytime i remember it i feel like i sabotaged myself, it was a small thing i blew out of proportion for no reason. It's been over 6 months now and we've nc, it kills me that we don't even check up on eachother. It's like neither of us exist and the year we spent together wasn't even real. Every now and then I'm bombarded with memories of her, things she used to say, how she used to text, how she looked, how she sounds, i still check her socials sometimes and i end up feeling worse. idk if she misses me as much as i miss her or even at all. there are no traces or hints of anything like that on her socials, she never put me on any of them to begin with. I just need help letting go, moving on, I've thrown myself into work and my company for the most part but the feeling of loss still eats at me sometimes. I know it was probably the best thing for me cause i was getting pretty lazy n comfortable in the relationship and not taking care of my body n my career, but now that i am more successful and working harder than i ever have i just feel like there's something missing.
