You cannot live for or account for your mistakes through other people.
You cannot make anyone else accept their own flaws or mistakes no matter how they’ve impacted you - sometimes you simply have to take up the responsibility of moving on & progressing despite that hurt.
Who are you without the things you feel define you? Do you have an identity that exists outside of these things or if any of these things were to fall apart would you be? Or would you again be lost as a result of suffering from loss?
