I’m 78-years-old and struggle with rethinking past mistakes. Honestly, most people do. What helped me was joining a grief group that grew into a support group with other women who learned each other’s darkest secrets and felt safe to share. I was suffering with suicide ideation and being able to discuss it was immensely helpful. The old saying: We are only as sick as our secrets, is very true. It takes guts to open up.
I hope this helps you in some way❤️ I wish you the very best.
