How to undo my mistakes?

[qpsns]

I have had countless mistakes that I've made in my life and people wouldn't forgive me.
How do I undo these mistakes?

We have to live with some mistakes, while others can be amended. It depends.

What is done can never be undone... But sometimes damage can be healed, or you can put in effort to make amends to the best of your ability, and try to avoid making the same mistakes again in the future. Sometimes you can try your best to make things better but there is nothing that can be done, in that case you should try to accept it. Mistakes do not always deserve to be forgiven, unfortunately.
