How to move on from a bad breakup?

My girlfriend and I broke up, it was a bad argument and mainly my fault. I’ve apologised, gave her space and respected her decision that she wants nothing to do with me due to her blocking me a few weeks later despite us having no contact. I am trying to move on but I can’t stop thinking about her and how guilty I feel about screwing everything up. I’ve come to terms with the fact that I don’t deserve another chance and she clearly feels the same but I’m just looking for advice on how to move on from this and stop hurting.
