My heart to yours. I’m so grateful you were able to break away from your childhood memories to build the life you imagined for yourself. Fantastic that your siblings did well. Every child/parent relationship is different and every individual meets challenges in their own unique way. It’s wonderful that you have the opportunity to be part of their family units as an aunt and let these new and better relationships be the ones you remember and cherish.
Yes; I love being an aunt! My nephew told me not long ago that I’m a “closet mother”. LOL!
Also loved the cats we’ve had for the last 30+ years. Now down to two and we’ll have no more.
