It’s not weird. I would affirm yourself that they did not do everything right, and the things you’re angry about you have good reason to be. But let the anger and hate fade. They were probably trying their best. And the older you get the more you realize that we are all winging it. Now that you are an adult you can set healthy boundaries and interact with them on your own terms.

There’s some stockholm syndrome between children and parents and I think it’s natural to get angry as you move past that. But as an adult you can have a relationship with them where you see them more as flawed peers than omnipotent parents. Of course not everyone will want to have that relationship, but if you can and want to then I think it’s worth it.
