How do you move forward after hurting people?

I cut off my friends because I felt mistreated, but I didn’t explain anything at the time because I didn’t know how to handle it. I can see how my actions hurt them, even if it was never my intention, and that has been weighting on me so much.

I don’t know how to deal with the guilt without letting it consume me, and I don’t know how to move forward knowing I hurt people I cared about. How does someone deal with the fact that they messed up and hurt people? I’d appreciate advice on this, rather than opinions on what I did wrong.
