I hear what you are saying. I truly believe some parents aren't fit to have children.

In my own personal life, though, through speaking to my psychologist and going through intensive counselling, I have learned that some of my thinking at times can be off and the way that I perceive things is not what they actually are.

I can't say in your case because I don't know everything you're going through / have been through. But a trained professional in psychotherapy can help you navigate your feelings if what you say is true.
