Wow so much pain and remorse in your words. But so much power and strength. On a personal level, not as a reader, I admire the voice here and the wisdom. That is the right choice. I wonder what and how much it took you to realize that, for me it took a lot. Being affected by toxic people you love no matter what kind of relation you have with them could burn your soul, literally.
You poured your heart out here and that is the 1st and key step! Stay strong. Well written and thanks for sharing.
