If you make the decision to change yourself and behave differently, you become a new person. It’s OK to dislike the old you while loving the new you. That’s how to deal with regret.
Am I a good man?
Forgive yourself your past & focus on being the best person you can be in the future. Just by asking, “am I a good person?” it shows you care and can act from that feeling. You’re doing fine!
