Как исправить ошибки прошлого? Дети - лучшее, что было, но жалею о решениях. Что делать?

I hate that my kids are so loving yet get treated so weird different and unfair my kids are literally the best thing that could’ve ever happened to me but I really wish I carefully considered having kids by a better person I just wish I could go back in time I feel like they are in such a terrible situation because of my mistake. I feel like I owe it to them to make better decisions seeing how it affects them and I just pray they have healthier bonds and relationships.
