The 60s and 70s (for me) had no awareness of my problems. Only now am I discovering that I did what I could, but I wasn’t equipped to deal with people well.
It’s too late for me, but I’m glad kids today have more resources, although the problems are just as hard to navigate.
God bless you all.
Apologizing to them is also enough to forgive yourself. Regardless if they won’t accept the apology, you’ve grown enough to recognize past mistakes, and made reasonable attempts to amend them, there’s no need to dwell on it any longer. It’s okay to try and make the past right, and move forward with what You’ve learned and continue to grow as a person.
